Summary: Increase number of client retries/ failovers to OMs
Key: HDDS-5059
URL: https://issues.apache.org/jira/browse/HDDS-5059
Project: Apache Ozone
Issue Type: Improvement
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
Currently in an OM HA setup, client by default does 15 failovers before giving
up. If there are 3 OMs and a leader has not been elected yet, then the client
will try each OM in a round robin way, wait for 2 secs and then try all the OMs
again. This gives the client around 10 seconds before it exhausts all its
failover attempts and fails.
This Jira proposes to increase the failover attempts and the exponentially
increase the wait between failovers to same OM after a few times. The client
should not give up easily if the OMs are in the process of electing a leader.
