Bharat Viswanadham updated HDDS-3046:
-------------------------------------
Status: Patch Available (was: Open)
> Fix Retry handling in ozone RPC Client
> --------------------------------------
>
> Key: HDDS-3046
> URL: https://issues.apache.org/jira/browse/HDDS-3046
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
> Labels: OMHA, pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Right now for all other exceptions other than serviceException we use
> FailOverOnNetworkException.
> This Exception policy is created with 15 max fail overs and 15 retries.
>
> {code:java}
> retryPolicyOnNetworkException.shouldRetry(
> exception, retries, failovers, isIdempotentOrAtMostOnce);{code}
> *2 issues with this:*
> # When shouldRetry returns action FAILOVER_AND_RETRY, it will stuck with
> same OM, and does not perform failover to next OM. As
> OMFailoverProxyProvider#performFailover() is a dummy call does not perform
> any failover.
> # When ozone.client.failover.max.attempts is set to 15, now with 2 policies
> with each set to 15, we will retry 15*2 times in worst scenario.
