Hi - i've OpenTSDB v2.2.1 installed on HDP 2.4 , and i'm getting the following error on start up :

I've tried unistalling & re-installing OpenTSDB, but the error persists.

Any ideas ?

Command :-

The issue is fixed, there was a conflict since the map-reduce component (which was also added to the classpath) has a different netty jar from the one used by OpenTSDB.

I've removed the map-reduce jars from the CLASSPATH to fix the issue.
