some classes from streaming provided by dependencies are overriding with different implementation the solution is to move all classes from package org.apache.kafka to shade my spark version is 2.4.1 here the plugin for maven build <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>2.4.3</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <relocations> <relocation> <pattern>org.apache.kafka</pattern> <shadedPattern>shade.org.apache.kafka</shadedPattern> </relocation> </relocations> </configuration> </execution> </executions> </plugin>

Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper]. @dbains you should update

Problem: In HDP 2.3.4 and Ambari 2.4.2, Storm nimbus was not coming up: 2017-05-30 14:35:18.756 o.a.t.s.TThreadPoolServer [ERROR] Error occurred during processing of message.
java.lang.RuntimeException: No nimbus leader participant host found, have you started your nimbus hosts?? Following is the error from Nimbus log: 2017-05-30 14:35:18.750 b.s.d.nimbus [WARN] principal: storm@EXAMPLE.COM is trying to impersonate principal: ambari-server@EXAMPLE.COM
2017-05-30 14:35:18.751 b.s.d.nimbus [WARN] impersonation attempt but nimbus.impersonation.authorizer has no authorizer configured. potential
security risk, please see SECURITY.MD to learn how to configure impersonation authorizer.
2017-05-30 14:35:18.756 o.a.t.s.TThreadPoolServer [ERROR] Error occurred during processing of message.
java.lang.RuntimeException: No nimbus leader participant host found, have you started your nimbus hosts?
Cause: Property ''nimbus.impersonation.authorizer" was set to 'org.apache.storm.security.auth.authorizer.ImpersonationAuthorizer'. Prior to HDP 2.5, the storm package was backtype instead of org.apache. Solution: Modify the property as follows: nimbus.impersonation.authorizer=backtype.storm.security.auth.authorizer.ImpersonationAuthorizer

Problem Description: Unable to start storm nimbus from Ambari, throwing following error: raise ExecutionFailed(err_msg, code, out, err)
resource_management.core.exceptions.ExecutionFailed: Execution of 'ambari-sudo.sh ln -s /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common-*.jar /usr/hdp/current/storm-nimbus/lib/ambari-metrics-storm-sink.jar' returned 1. ln: target `/usr/hdp/current/storm-nimbus/lib/ambari-metrics-storm-sink.jar' is not a directory Cause: Two legacy jars under storm lib: # ls -ld /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common*
-rw-r--r-- 1 root root 1937430 May 11 15:57 /usr/lib/storm/lib/ambari-metrics-storm-sink-legacy-with-common-2.4.1.0.22.jar

Cause: 1. Few storm configs were still configured with backtype packages 2. Stale states in zookeeper and local data Solution: 1. Filtered in the configs and changed all the backtype packages to org.apache as Storm from HDP 2.5 onwards uses org.apache packages.
2. Follow below steps to clear stale states and local data:
-> Deactivate all running topologies.
-> Stop Storm service
-> Delete all states under zookeeper: $/usr/hdp/current/zookeeper-client/bin/zkCli.sh (optionally in secure environment specify -server zk.server:port)
> rmr /storm -> Delete all states under the storm-local directory. Please make sure to run this on all storm hosts: $ rm -rf <value of stormlocal.dir> -> Start storm service.
