@Aditya Sirna, It seems like a bug with Ambari (https://issues.apache.org/jira/browse/AMBARI-22286) One way to workaround this is to remove the jmxetric param from supervisor.childopts , nimbus.childopts and worker.childopts and restart storm. If you a want a jar, then please find the attached jar. Extract the jar and put it in (/usr/hdp/{hdp-version}/storm/contrib/storm-jmxetric/lib/)jmxetric-jar.zip Thanks, Aditya ... View more

@Theyaa Matti, I guess you are using 'http' transport mode for sending RPC messages. Can you please try changing it to binary and see if it works. set 'hive.server2.thrift.bind.host' to 'localhost' and 'hive.server2.transport.mode' to 'binary' in hive-site.xml and restart Hive Thanks, Aditya ...
