------------------------------------
Summary: Change OMNotLeaderException logging to DEBUG
Key: HDDS-3847
URL: https://issues.apache.org/jira/browse/HDDS-3847
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
In a OM HA setup, client tries the OM's in a round robin fashion to find the
leader OM. It is not required to log the retry information for every client
call. It creates noise on the console. Instead, we should just log the retry
attempts only when all the retries fail.

protocolPB.Hadoop3OmTransport: RetryProxy: OM:om1 is not the leader. Suggested
leader is OM:om3. at
