Which version of HDP are you using ? Can you post the full stack trace ?

kafka-consumer-groups.sh calls ConsumerGroupCommand Please take a look at the following method: ConsumerGroupCommand#getPartitionOffsets

bq. Thread.sleep("sometime"); How long was the sleep ? I might be possible that compaction finished after the sleep. Which HDP version are you using ?

Before PHOENIX-3288 is resolved, please set phoenix.schema.isNamespaceMappingEnabled to true. hbase-site.xml should be on the classpath

For hbase, you can obtain configuration from the following URL: master-node:16010/conf

bq. is there a different version for Netty required ? As I said above, HDP 2.4 came with 3.2.4.Final which is different from 3.9.4.Final (opentsdb built with)

bq. OpenTSDB only has Netty 3.2.4 jar But the list below showed netty-3.9.4.Final.jar

tyu · ‎01-03-2017

As you can see, there are two netty jars on the classpath with different version. I am not aware of plan to support OpenTSDB. See if you can build OpenTSDB with the netty version hbase uses. Shading is another option but I am not expert there.
