> Key: HDDS-5872
> URL: https://issues.apache.org/jira/browse/HDDS-5872
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
> Priority: Major
> Labels: pull-request-available
>
> 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.
