Agent configuration for 'a1' has no configfilters

I got an error(Agent configuration for 'a1' has no configfilters) when I use flume 1.9 to transfer the data from kafka to HDFS, but no other error or info were reported.
The source I used is KafkaSource, sink is file sink.
Interceptor I used is self-define which I will show bolow.
Agent configuration for 'a1' has no configfilters.
the logger info is below. differ from other question, the

OutputSream.write is too slow

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
#
$Response = $ua->request(POST $remoteHost ,
Content_Type => 'form-data',
Authorization => $Authorization,
'Proxy-Authorization' => $Proxy_Authorization ,

]
);
unless ($Response->is_success) {
my $Msg = $Response->error_as_HTML;
# Remove HTML tags - we're in a DOS shell!
$Msg =~ s/<[^>]+>//g;
print "ERROR! SERVER RESPONSE:\n$Msg\n";
print "$remoteHost\n\n" if $Options{'v'};
Error "Could not connect to " . $remoteHost ;
}
my $Result2 = $Response->content();
Error "Abnormal termination...\n$Result2" if $Result2 =~ /_APP_ERROR_/;
open(F, ">$dl_filename") or Error "Could not open '$dl_filename'!";
binmode F; # unless $dl_filename =~ /\.txt$|\.htm$/;
print F $Result2;
close F;
print "received.\n";
}

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.

Not able to change quantity of a commerceItem using handleSetOrderByCommerceId

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:
for (CommerceItem cI : commerceItems) {
if (isLoggingDebug()) {
logDebug("inside handleRemoveItemFromOrder : commerceItems iteration : "+cI.getId() +" : "+ cI.getCatalogRefId());
}
request.setParameter(cI.getId(), cI.getQuantity());
if(cI.getCatalogRefId().equals(dealTobeDeleted)){
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);
}
}else{
String[] dealArray = new String[]{cI.getId()};
repoItemIdOfCommerceItemGettingRemoved = cI.getCatalogRefId();
setRemovalCommerceIds(dealArray);
if (isLoggingDebug()) {
logDebug("inside handleRemoveItemFromOrder : before super call handleRemoveItemFromOrder : "+repoItemIdOfCommerceItemGettingRemoved +" : "+getRemovalCommerceIds().length);
}
break;
}
}
}

Getting Null results for query on DB2 using Spring

If i run the query through Quantum DB i do get the desired result. But when same query is used in the code no error is thrown and i get no result.
Query:
final String RECORD_LIST_QUERY = "SELECT COUNT(*) FROM A.abc AS WEU WHERE WEU.ZZAA_AUFT_NR = '?'";
final String FZEG_NR_QUERY="SELECT WEU.FZEG_NR, WEU.ZZAA_AUFT_NR FROM A.abc AS WEU WHERE WEU.ZZAA_AUFT_NR = '?'";
Method:
public OrderDetailsDto FetchOrderData(OrderDetailsDto orderDetailsDto) {
System.out.println("DAO:through DTO: Order Nr before running query " + orderDetailsDto.getOrderNr());
Object args = orderDetailsDto.getOrderNr();
OrderDetailsDto orderDetailsDtoCopy = new OrderDetailsDto();
System.out.println("Data source is " + getDataSource());
try {
List<Map<String, Object>> result = getJdbcTemplate().queryForList(IOrderDao.FZEG_NR_QUERY, args);
if (result.listIterator().hasNext()) {
System.out.println("DAO:through DTO: Order Nr before running query " + args);
System.out.println("Result to check query is fired " + result.get(result.listIterator().nextIndex()));
} else {
System.out.println("DAO:through DTO: Order Nr before running query " + args);
int cnt = getJdbcTemplate().queryForInt(IOrderDao.RECORD_LIST_QUERY, args);
System.out.println("count of record is " + cnt);
}
for (Map<String, Object> record : result) {
System.out.println("In Dao FOR Loop");
orderDetailsDtoCopy.setOrderNr("" + record.get("ZZAA_AUFT_NR"));
orderDetailsDtoCopy.setFZEGNr("" + record.get("FZEG_NR"));
}
System.out.println("In dao order number is set as " + orderDetailsDtoCopy.getOrderNr());
System.out.println("In dao FZEG number is set as " + orderDetailsDtoCopy.getFZEGNr());
} catch (DataAccessException e) {
e.printStackTrace();
}
return orderDetailsDtoCopy;
}

Twitter4j authentication credentials are missing

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:
