[jira] [Created] (HDDS-1718) Increase Ratis Leader election timeout default to 10 seconds.

Aravindan Vijayan created HDDS-1718:
---------------------------------------

             Summary: Increase Ratis Leader election timeout default to 10 seconds.
                 Key: HDDS-1718
                 URL: https://issues.apache.org/jira/browse/HDDS-1718
             Project: Hadoop Distributed Data Store
          Issue Type: Task
          Components: Ozone Datanode
            Reporter: Aravindan Vijayan
            Assignee: Aravindan Vijayan
             Fix For: 0.4.1


While testing out ozone with long running clients which continuously write data, it was noted that whenever a 1 second GC pause occurs in the leader, it triggers a leader election thereby disturbing the steady state of the system for more time than the GC pause delay.
