------------------------------------
Summary: Do not failover on some RpcExceptions
Key: HDDS-5872
URL: https://issues.apache.org/jira/browse/HDDS-5872
Project: Apache Ozone
Issue Type: Improvement
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
When OMFailoverProxy encounters an RpcException, we should check if a failover
or retry is required or not.
For example, if the response length exceeds ipc.maximum.response.length on one
OM, it will exceed the limit on all OMs. So we do not need to do a retry or
failover.
If there is an RpcNoSuchMethodException, RpcNoSuchProtocolException or
VersionMismatch Exception etc. on only 1 OM and not of others, it could lead to
state divergence between the OMs. So it would be better to fail the request
than to retry on other nodes.
