[jira] [Created] (HDDS-4388) Make writeStateMachineTimeout retry count proportional to node failure timeout

Shashikant Banerjee created HDDS-4388:
-----------------------------------------

             Summary: Make writeStateMachineTimeout retry count proportional to node failure timeout
                 Key: HDDS-4388
                 URL: https://issues.apache.org/jira/browse/HDDS-4388
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee
             Fix For: 1.1.0


Currently, in ratis "writeStateMachinecall" gets retried indefinitely in event of a timeout. In case, where disks are slow/overloaded or number of chunk writer threads are not available for a period of 10s, writeStateMachine call times out in 10s. In cases like these, the same write chunk keeps on getting retried causing the same chink of data to be overwritten. The idea here is to abort the request once the node failure timeout reaches.
