----------------------------------------
Summary: Fix Retry handling in Rpc Client
Key: HDDS-3046
URL: https://issues.apache.org/jira/browse/HDDS-3046
Project: Hadoop Distributed Data Store
Issue Type: New Feature
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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.
