How to solve this exception?

The error here is pretty self explanatory: you can’t have more than one connection to a distributed system within a single JVM. In this particular case you’re starting both a server cache (ServerLauncher) and a client cache (ClientCacheFactory) within the same JVM, which is not supported.
To solve the issue, use two different applications or JVMs, one for the server and another one for the client executing the query.
Cheers.

Kafka Topic creation from Java API [duplicate]

This question already has answers here:
How to create a Topic in Kafka through Java
(6 answers)
Closed 1 year ago.
I am trying to create a Kafka topic using Java API, but getting LEADER is NOT AVAILABLE.
Code:
int partition = 0;
ZkClient zkClient = null;
try {
String zookeeperHosts = "localhost:2181"; // If multiple zookeeper then -> String zookeeperHosts = "192.168.20.1:2181,192.168.20.2:2181";
int sessionTimeOutInMs = 15 * 1000; // 15 secs
int connectionTimeOutInMs = 10 * 1000; // 10 secs
zkClient = new ZkClient(zookeeperHosts, sessionTimeOutInMs, connectionTimeOutInMs, ZKStringSerializer$.MODULE$);
String topicName = "mdmTopic5";
int noOfPartitions = 2;
int noOfReplication = 1;
Properties topicConfiguration = new Properties();
AdminUtils.createTopic(zkClient, topicName, noOfPartitions, noOfReplication, topicConfiguration);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (zkClient != null) {
zkClient.close();
}
}
Error:
[2017-10-19 12:14:42,263] WARN Error while fetching metadata with correlation id 1 : {mdmTopic5=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)

[2017-10-19 12:14:42,479] WARN Error while fetching metadata with correlation id 4 : {mdmTopic5=LEADER_NOT_AVAILABLE} (org.apache.kafka.clients.NetworkClient)
Does Kafka 0.11.0.1 supports AdminUtils.??? Please let me know how to create topic in this version.
Thanks in Advance.

Since Kafka 0.11 there is a proper Admin API for creating (and deleting) topics and I'd recommend to use it instead of directly connecting to Zookeeper.
See AdminClient.createTopics(): http://kafka.apache.org/0110/javadoc/org/apache/kafka/clients/admin/AdminClient.html#createTopics(java.util.Collection)

Generally LEADER NOT AVAILABLE points to network issues rather than issues with your code.
Try:
telnet host port to see if you can connect to all required hosts/ports from your machine.
However, the latest approach is to use the BOOTSTRAP_SERVERS while creating topics.
A working version of topic creation code using scala would be as follows:
Import the required kafka-clients using sbt.
// https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients
libraryDependencies += Seq("org.apache.kafka" % "kafka-clients" % "2.1.1")
The code for topic creation in scala:
import java.util.Arrays
import java.util.Properties
import org.apache.kafka.clients.admin.NewTopic
import org.apache.kafka.clients.admin.{AdminClient, AdminClientConfig}
class CreateKafkaTopic {
def create(): Unit = {
val config = new Properties()
config.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "192.30.1.5:9092")
val localKafkaAdmin = AdminClient.create(config)
val partitions = 3
val replication = 1.toShort
val topic = new NewTopic("integration-02", partitions, replication)
val topics = Arrays.asList(topic)
val topicStatus = localKafkaAdmin.createTopics(topics).values()
//topicStatus.values()
println(topicStatus.keySet())
}
}
Hope it helps.

$jasperDesign->setQuery($query);

$report = $compileManager->compileReport($jasperDesign); } catch (JavaException $ex) {
echo $ex; }
$fillManager = new JavaClass("net.sf.jasperreports.engine.JasperFillManager"); //aqui se pasan los parametros (Fecha Inicio y Fecha Fin)
$params = new Java("java.util.HashMap");
$date=new Java('java.util.Date',$Param1);
$date1=new Java('java.util.Date',$Param2);
$params->put("FInicio",$date);
$params->put("FFin",$date1);
$class = new JavaClass("java.lang.Class"); $class->forName("com.mysql.jdbc.Driver"); $driverManager = new JavaClass("java.sql.DriverManager");
//db username and password
$conn = $driverManager->getConnection("jdbc:mysql://localhost/viajestrafico?zeroDateTimeBehavior=convertToNull", "root", "root"); $jasperPrint = $fillManager->fillReport($report, $params, $conn);
$exporter = new java("net.sf.jasperreports.engine.JRExporter");
And sql query in ireports:

Looking to your error message, the java.util.Date cannot be created with '12/Feb/16':
java_Client->createObject('java.util.Date', Array)
#5 C:\wamp\www\advanced\backend\javabridge\generate.php(49):
Java->Java('java.util.Date', '12/Feb/16') #6 {main}] in
If you want to instanciate a java date object, use the java.util.Date(long date) constructor which accepts a timestamp expressed in milliseconds :
<?php
$startDate = $_POST['FInicio']; // better to filter this :)
$Param1 = strtotime($startDate) * 1000; // to get milliseconds
if ($Param1 == 0) {
throw new Exception("FInicio date parameter could not be parsed");
}
// ...
$javaDate = new Java('java.util.Date',$Param1); // This is a java date
Your $date parameter should now be a valid java.util.Date object.
You can test it :
$simpleDateFormat = new Java("java.text.SimpleDateFormat", 'yyyy-MM-dd');
echo $simpleDateFormat->format($javaDate);
// should print your date in Y-m-d format
Alternatively, you can parse the date in Java through the java.text.SimpleDateFormatter object:
$date = '2016-12-21';
$simpleDateFormat = new Java("java.text.SimpleDateFormat", 'yyyy-MM-dd');
$javaDate = $simpleDateFormat->parse($date); // This is a Java date
Both approaches works...
JasperReport issue with date
Not exactly linked to your question, but if you want to use your Date as a query parameter you should use the java.sql.Date(long date) object instead of java.util.Date... Here's a little dirty snippet to summarize changes:
// php
$sqlDate = new Java('java.sql.Date', strtotime($_POST['FInicio']) * 1000));
$params->put('FInicio', $sqlDate);
// in your report header (.jrxml):
<parameter name="FInicio" class="java.sql.Date">
// in your report query (.jrxml):
$P{FInicio} <= chofer_situacion_laboral.`FechaInicio`
You can also have a look to the soluble-japha javabridge client (refactored Java.inc client), the syntax differs a bit but there's a documentation about dates that might reveal useful.

It was simple, just a problem I had from the beginning in php code.
$query = new java("net.sf.jasperreports.engine.design.JRDesignQuery");
$jasperDesign->setQuery($query);
This code was preventing xrml query from executing, because it was creating a query object empty.

I'm currently using Cloudera quick start VM to test this.
The problem is; if i run this very code on VM it works absolutely fine. But it fails with below error if it is run from outside. And I'm suspecting it has something to do with the VM setting rather than anything else. Please note that I've already checked if I can connect to the node manager / job tracker of the VM from host machine and it works absolutely fine. When I run the code from my host OS instead of running it on VM; I get the below error :

But I see no trace of any activity in Master or RegionServer log.
Please note that my host OS is Mac OSX 10.7.5
As per the resource available; this should work fine; though some suggest the simple HBase java client never works. I'm confused; and eagerly waiting for pointers !!! Please reply

start your hiveserver2 on different port and then try connecting
command to connect hiveserver2 on different port (make sure hive is in path ) :
hive --service hiveserver2 --hiveconf hive.server2.thrift.port=13000

The HBase Java client certainly does work!
The most likely explanation is that your client can't see the machine that the master is running on for some reason.
One possible explanation is that, although you are connecting to Zookeeper using an IP address, the HBase client is attempting to connect to the master using its hostname.
So, if you ensure that you have entries in your hosts file (on the client) that match the hostname of the machine running the master, this may resolve the problem.
Check that you can access the master Web UI at <hostname>:60010 from your client machine.
