Hi. Am trying to run the hdp25experiment on HDP2.5 sandbox. And am getting exceptions in topology execution in Kafka Spout and HBaseBolts. Please suggest why this could be hapenning?

I am getting the following exceptions in Storm View:

sandbox.hortonworks.com:6700java.lang.ExceptionInInitializerError at kafka.metrics.KafkaMetricsGroup$class.newTimer(KafkaMetricsGroup.scala:85) at kafka.consumer.FetchRequestAndResponseMetrics.newTimer(FetchRequestAndResponseS

Two questions:

1. What version of the sandbox are you running?

With the latest sandbox you should not get the kafkaSpout errors.

2. Is your HBase service up and running?

HBase Master, RegionServer

Usually HBase tends to go down, so I would suggest deactivating services you don't need such as Flume, Oozie, Zeppelin

Thanks for the prompt response. I am using HDP 2.5 sandbox. With HDP 2.4, the topology was not getting deployed due to Storm version mismatch errors.

Am observing these same run-time errors on an HDP 2.5 three node cluster.

I had to make a change to the storm-streaming POM. It was looking for version 2.5.1.0-9 of HDP whereas the currently downloadable version is 2.5.0.0-1245 for both HDP and sandbox. I do not know if this is causing the problem.

Hello Rashmi,

Can you let me know the version of HDP sandbox using "sandbox-version" command.

I am running:

[root@sandbox ~]# sandbox-version

Sandbox information:

Created on: 30_09_2016_09_43_28 for

Hadoop stack version: Hadoop 2.7.3.2.5.0.0-1245

Ambari Version: 2.4.0.0-1225

Ambari Hash: 59175b7aa1ddb74b85551c632e3ce42fed8f0c85

Ambari build: Release : 1225

Java version: 1.8.0_101

OS Version: CentOS release 6.8 (Final)

With the sandbox-version above, I am able to successfully run the topology. Do you have the same version or newer build?

@Rashmi

I`m running the exactly same version of sandbox as yours:

Created on: 25_10_2016_08_11_26 for

Hadoop stack version:

Hadoop 2.7.3.2.5.0.0-1245

Ambari Version: 2.4.0.0-1225

Ambari Hash: 59175b7aa1ddb74b85551c632e3ce42fed8f0c85

Ambari build: Release : 1225

Java version: 1.8.0_111

OS Version: CentOS release 6.8 (Final)

And I`m having the same error as @Rashmi Varma reported.

Answering @jmedel question: Yes, my HBase services are all up and running fine

Someone solve this?
