I'm trying to add 1 to a number, and then get the new number back.
I can't get my UpdateItemSpec right. Please help. Every example out there seems to show something different and none of it is working.
Here is my code:
AmazonDynamoDBClient dbClient = new AmazonDynamoDBClient(
new BasicAWSCredentials("SECRET", "SECRET")
);
dbClient.setRegion(Region.getRegion(Regions.fromName("us-west-1")));
DynamoDB dynamoDB = new DynamoDB(dbClient);
Table table = dynamoDB.getTable("NumTable");
GetItemSpec spec = new GetItemSpec()
.withPrimaryKey("PKey","OrderNumber");
Item item = table.getItem(spec);
logger.info(item.toJSONPretty());
UpdateItemSpec updateItemSpec = new UpdateItemSpec()
.withPrimaryKey("Pkey",
"OrderNumber")
.withReturnValues("UPDATED_NEW")
.withUpdateExpression("ADD #k :incr")
.withNameMap(new NameMap().with("#k", "NumVal"))
.withValueMap(
new ValueMap()
.withNumber(":incr", 1));
//.withString(":incr", "{N:\"1\"}"));
//I've tried a million other ways too!
UpdateItemOutcome outcome = table.updateItem(updateItemSpec);
logger.info(outcome.getItem().toJSONPretty());
Console shows the first get part working:
Sat Nov 09 00:46:07 UTC - 2019-11-09 00:46:07 f1475303-7585-4804-8a42-2e0a9b16b1dc INFO Commission:88 - {

Sat Nov 09 00:46:07 UTC - "PKey" : "OrderNumber"
Sat Nov 09 00:46:07 UTC - }
But the update part gives this error (among others):
Sat Nov 09 00:46:08 UTC - The provided key element does not match the schema (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException; Request ID: 8TPDT2EVMC0G0GF3IFK7SU6777VV4KQNSO5AEMVJF66Q9ASUAAJG): com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException com.amazonaws.services.dynamodbv2.model.AmazonDynamoDBException: The provided key element does not match the schema (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException; Request ID: 8TPDT2EVMC0G0GF3IFK7SU6777VV4KQNSO5AEMVJF66Q9ASUAAJG) at [........]
I really feel like the key element does match the schema :'(
Here is a picture from my AWS console:
Your implementation looks fine to me. The error is because of typo error in your UpdateItemSpec code.
UpdateItemSpec updateItemSpec = new UpdateItemSpec()
.withPrimaryKey("Pkey",
"OrderNumber")
The typo is "Pkey". It should be "PKey", which is why it works in GetItemSpec code.

I recently started programming with Esper and I have a smart wearable that sends pedometer data to my laptop. I then process this data using esper. But suppose I have multiple smart wearables with each an unique MAC address. I use time windows and my question is how can I change my rule file so that the rules only fire for events with the same macaddress and take appropiate action based on this MAC address. My initialization and rule are:
Configuration cepConfig = new Configuration();
cepConfig.addEventType("Steps", Steps.class.getName());
// We setup the engine
EPServiceProvider cep = EPServiceProviderManager.getProvider("myCEPEngine", cepConfig);
EPRuntime cepRT = cep.getEPRuntime();
// We register an EPL statement
EPAdministrator cepSteps1 = cep.getEPAdministrator();
EPStatement cepStatementSteps1 = cepSteps1.createEPL("select * from "
+ "Steps().win:time(1 hour) "
+ "group by macAddress "
+ "having sum(max(steps)-min(steps)) < 100");
cepStatementSteps1.addListener(new rule1Listener());
My Steps class has the following fields:
double steps;
String stepsTimestamp;
String macAddress;
And this is how I insert the events:
Steps steps0 = new Steps(0, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps0);
Steps steps00 = new Steps(0, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps00);
Steps steps1 = new Steps(25, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps1);
Steps steps2 = new Steps(50, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps2);
Steps steps3 = new Steps(55, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps3);
Steps steps4 = new Steps(105, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps4);
Steps steps5 = new Steps(75, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps5);
Steps steps6 = new Steps(110, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps6);
This is my output:
Sending tick: Steps: 0.0 Timestamp: Mon Mar 14 18:13:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 0.0 Timestamp: Mon Mar 14 18:18:23 CET 2016 Mac Address: LD24ESF7474
->Rule 1 fired: LD24ESF7474
Sending tick: Steps: 25.0 Timestamp: Mon Mar 14 18:23:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 105.0 Timestamp: Mon Mar 14 18:28:23 CET 2016 Mac Address: LD24ESF7474
Sending tick: Steps: 55.0 Timestamp: Mon Mar 14 18:33:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 75.0 Timestamp: Mon Mar 14 18:38:23 CET 2016 Mac Address: K5E45H778
Sending tick: Steps: 110.0 Timestamp: Mon Mar 14 18:43:23 CET 2016 Mac Address: K5E45H778
Why doesn't the rule fire for the one but last event of 75 steps?
The SQL-standard "group by" clause is for aggregation per group. Thus just adding "group by macAddress" should get it done.
I am encountering with a senerior like this:
My project has a servlet to catch a request from perl. The request is to download a file. The request is a multipartRequest.
#RequestMapping(value = "/*", method = RequestMethod.POST)
public void tdRequest(#RequestHeader("Authorization") String authenticate,
HttpServletResponse response,
HttpServletRequest request) throws Exception
{
if (ServletFileUpload.isMultipartContent(request))
{
ServletFileUpload sfu = new ServletFileUpload();
FileItemIterator items = sfu.getItemIterator(request);
while (items.hasNext())
{
FileItemStream item = items.next();
if (("action").equals(item.getFieldName()))
{
InputStream stream = item.openStream();
String value = Streams.asString(stream);
if (("upload").equals(value))
{
uploadRequest(items, response);
return;
}
else if (("download").equals(value))
{
downloadRequest(items, response);
return;
}
The problem is not here, it appears on the downloadRequest() function.
void downloadRequest(FileItemIterator items,
HttpServletResponse response) throws Exception
{
log.info("Start downloadRequest.......");
OutputStream os = response.getOutputStream();
File file = new File("D:\\clip.mp4");
FileInputStream fileIn = new FileInputStream(file);
//while ((datablock = dataOutputStreamServiceImpl.readBlock()) != null)
byte[] outputByte = new byte[ONE_MEGABYE];
while (fileIn.read(outputByte) != -1)
{
System.out.println("--------" + (i = i + 1) + "--------");
System.out.println(new Date());
//dataContent = datablock.getContent();
System.out.println("Start write " + new Date());
os.write(outputByte, 0,outputByte.length);
System.out.println("End write " + new Date());
//System.out.println("----------------------");
}
os.close();
}
}
I try to read and write blocks of 1MB from the file. However, it takes too long for downloading the whole file. ( my case is 20mins for file of 100MB)
I try to sysout and I saw a result like this:
The first few blocks can read, write data realy fast:
--------1--------
Mon Dec 07 16:24:20 ICT 2015
Start write Mon Dec 07 16:24:20 ICT 2015
End write Mon Dec 07 16:24:21 ICT 2015
--------2--------
Mon Dec 07 16:24:21 ICT 2015
Start write Mon Dec 07 16:24:21 ICT 2015
End write Mon Dec 07 16:24:21 ICT 2015
--------3--------
Mon Dec 07 16:24:21 ICT 2015
Start write Mon Dec 07 16:24:21 ICT 2015
End write Mon Dec 07 16:24:21 ICT 2015
But the next block is slower than the previous
--------72--------
Mon Dec 07 16:29:22 ICT 2015
Start write Mon Dec 07 16:29:22 ICT 2015
End write Mon Dec 07 16:29:29 ICT 2015
--------73--------
Mon Dec 07 16:29:29 ICT 2015
Start write Mon Dec 07 16:29:29 ICT 2015
End write Mon Dec 07 16:29:37 ICT 2015
--------124--------
Mon Dec 07 16:38:22 ICT 2015
Start write Mon Dec 07 16:38:22 ICT 2015
End write Mon Dec 07 16:38:35 ICT 2015
--------125--------
Mon Dec 07 16:38:35 ICT 2015
Start write Mon Dec 07 16:38:35 ICT 2015
End write Mon Dec 07 16:38:48 ICT 2015
The problem is in the os.write()
I realy cannot understand how the outputStream write, why it take such a long time like that? or I made some mistakes?
Sorry for my bad english. I realy need your support. Thank in advance!
This is the perl code from the client side
# ----- get connected to download the file

One problem is that fileIn.read(outputByte) can read random number of bytes, not only full outputByte. You read few KB, then you store full 1MB, and very fast you are running out of space on disk. Try this, notice the "readed" parameter.
void downloadRequest(FileItemIterator items,
HttpServletResponse response) throws Exception
{
log.info("Start downloadRequest.......");
OutputStream os = response.getOutputStream();
File file = new File("D:\\clip.mp4");
FileInputStream fileIn = new FileInputStream(file);
//while ((datablock = dataOutputStreamServiceImpl.readBlock()) != null)
byte[] outputByte = new byte[ONE_MEGABYE];
int readed =0;
while ((readed =fileIn.read(outputByte)) != -1)
{
System.out.println("--------" + (i = i + 1) + "--------");
System.out.println(new Date());
//dataContent = datablock.getContent();
System.out.println("Start write " + new Date());
os.write(outputByte, 0,readed );
System.out.println("End write " + new Date());
//System.out.println("----------------------");
}
os.close();
}
}
It looks like your download performance gets slower and slower, the further you are getting into the download. You start out at one or less seconds per block, by block 72 it is 7+ seconds per block and by block 128 it is 13 seconds per block.
There is nothing on the server side to explain this. Rather, it has the "smell" of the client side doing something wrong. My guess is that the client side is reading the data from the socket into an in-memory data structure, and that data structure (maybe just a String or StringBuffer or StringBuilder) is getting larger and larger. Either the time take to expand it is getting larger, or your memory footprint is growing and the GC is taking longer and longer. (Or both.)
If you showed us the client-side code .....
UPDATE
As I suspected, this line of code will be reading the entire content into the Perl equivalent of a string builder before turning it into a string.
my $Result2 = $Response->content();
Depending on how it is implemented under the hood, this will lead to repeated copying of the data as the builder runs out of buffer space and needs to be expanded. Depending on the buffer expansion strategy that Perl employs for this, it could give O(N^2) behavior, where N is the size of the file you are transferring. (The evidence is that you are not getting O(N) behavior ...)
If you want a faster downloads, you need to stream the data on the client side. Read the response content in chunks and write them to the output file. (I'm not a Perl expert, so I can't offer you code.) This will also reduce the memory footprint on the client side ... which could be important if your file sizes increase.
I am not able to change the quantity of commerceItem using handleSetOrderByCommerceId.PFB.
I am using Art Technology Group web commerce platform.
Here is my code snippet:

long quantity = cI.getQuantity();
//String currentSku = cI.getCatalogRefId();
if(quantity > 1){
// Set the new quantity for the commerce item being updated.
request.setParameter(cI.getCatalogRefId(), quantity-1);
setCheckForChangedQuantity(true);
result = super.handleSetOrderByCommerceId(request, response);
if (isLoggingDebug()) {
logDebug("inside handleRemoveItemFromOrder : after super call handleSetOrderByCommerceId : "+result);

I am trying to create a UDF for importing into Pig that matches a Regex pattern on a date. The Regex has been tested and works accordingly, but I am having trouble with the following code:
package com.date.format;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.apache.pig.EvalFunc;
import org.apache.pig.data.Tuple;
public class DATERANGE extends EvalFunc<String> {
#Override
public String exec(Tuple arg0) throws IOException {
try
{
String pattern = "(Oct\\W(?:1[5-9]|2[0-3])\\W(?:(?:0?9|10):\\d{2}:\\d{2}|11:00:00))";
Pattern pat = Pattern.compile(pattern);
Matcher match = pat.matcher((String) arg0.get(0));
if(match.find())
{
return match.group(0);
}
else return "none";
}
catch(Exception e)
{
throw new IOException("Caught exception processing input row ", e);
}
}
}
After compiling the above java code and exporting it as a jar and running it inside Hadoop using the following Pig script:
register 'DATEFormat.jar';
ld = LOAD 'dates/date_data_three' AS (date:chararray);
loop = foreach ld generate com.date.format.DATERANGE(date) as d:chararray;
dump loop;
I get the following error:

Does anybody know the correct way to implement a Java UDF for Pig that would work with the Regex I have provided?
Thanks
I recommend you to use REGEX_EXTRACT build-in command, this will be very easy instead of writing UDF.
ld = LOAD 'input.txt' AS (date:chararray);
loop = foreach ld generate REGEX_EXTRACT(date,'(Oct\\W(?:1[5-9]|2[0-3])\\W(?:(?:0?9|10):\\d{2}:\\d{2}|11:00:00))',1) as d:chararray;
C = FILTER loop by d is not null;
D = FOREACH C GENERATE $0;
DUMP D;
Output:
(Oct 15 09:26:09)
(Oct 23 10:26:09)
Your Regex UDF also working fine for me. i just copied your input and java code and executed locally. It works perfectly. Please see the below output that i got from your UDF code. I guess you may need to check your classpath are properly set or not.
(Oct 15 09:26:09)
(none)
(none)
(Oct 23 10:26:09)
(none)
(none)
Even better, you could use ToDate:
load your data into filtered_raw_financings_csvs with close_date as a chararray:
financings_csvs = FOREACH filtered_raw_financings_csvs
GENERATE name,
city,
state,
(close_date==''?NULL:ToDate(close_date, 'dd-MMM-yy')) AS close_date
;
Build your date format string as described here:
http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

I would like to make a tweet with Twitter4j in my Android app. Here is my code:
//TWITTER SHARE.
#Click (R.id. img_btn_twitter)
#Background
public void twitterPostWall(){
try {
//Twitter Conf.
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(CONSUMER_KEY)
.setOAuthConsumerSecret(CONSUMER_SECRET)
.setOAuthAccessToken(ACCESS_KEY)
.setOAuthAccessTokenSecret(ACCESS_SECRET);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
try {
RequestToken requestToken = twitter.getOAuthRequestToken();
Log.e("Request token: ", "" + requestToken.getToken());
Log.e("Request token secret: ", "" + requestToken.getTokenSecret());
AccessToken accessToken = null;
}
catch (IllegalStateException ie) {
if (!twitter.getAuthorization().isEnabled()) {
Log.e("OAuth consumer key/secret is not set.", "");
}
}
Status status = twitter.updateStatus(postLink);
Log.e("Successfully updated the status to [", "" + status.getText() + "].");
}
catch (TwitterException te) {
Log.e("TWEET FAILED", "");
}
}
I always get this error message from Twitter4j: java.lang.IllegalStateException: Authentication credentials are missing. See http://twitter4j.org/en/configuration.html for the detail. But as you can see I'm using builder to set my key. Can someone help me to fix it please? thanks.
Problem is following lines.
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = new TwitterFactory().getInstance();
You are passing the configuration to one TwitterFactory instance and using another TwitterFactory instance to get the Twitter instance.
Hence, You are getting
java.lang.IllegalStateException: Authentication credentials are missing
I suggest you to modify your code as follows:
//Twitter Conf.
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(CONSUMER_KEY)
.setOAuthConsumerSecret(CONSUMER_SECRET)
.setOAuthAccessToken(ACCESS_KEY)
.setOAuthAccessTokenSecret(ACCESS_SECRET);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
And use this twitter instance. It will work.
I was having issues with the configuration on Twitter4j because I was not providing the right configuration. So in order to fix it, I created the following function to establish my configuration to later be used in another function:
public static void main(String args[]) throws Exception {
TwitterServiceImpl impl = new TwitterServiceImpl();
ResponseList<Status> resList = impl.getUserTimeLine("spacex");
for (Status status : resList) {
System.out.println(status.getCreatedAt() + ": " + status.getText());
}
}
public ResponseList<Status> getUserTimeLine(String screenName) throws TwitterException {
TwitterFactory twitterFactory = new TwitterFactory(getConfiguration().build());
Twitter twitter = twitterFactory.getInstance();
twitter.getAuthorization();
Paging paging = new Paging(1, 10);
twitter.getId();
return twitter.getUserTimeline(screenName, paging);
}
public ConfigurationBuilder getConfiguration() {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("myConsumerKey")
.setOAuthConsumerSecret("myConsumerSecret")
.setOAuthAccessToken("myAccessToken")
.setOAuthAccessTokenSecret("myAccessTokenSecret");
return cb;
}
To get the required info, you must have a Twitter developer account, and to get the auth info of an app previously created go to: Projects and Apps.
In the end, I was able to retrieve the data from a SpaceX account:
