[jira] [Created] (RATIS-644) Handle failures encountered in applyLog

Supratim Deka created RATIS-644:
-----------------------------------

             Summary: Handle failures encountered in applyLog
                 Key: RATIS-644
                 URL: https://issues.apache.org/jira/browse/RATIS-644
             Project: Ratis
          Issue Type: Bug
          Components: server
            Reporter: Supratim Deka
            Assignee: Supratim Deka


This is related to HDDS-1739 which detects and reports IO failures during applyTransaction.

Currently, the StateMachineUpdater in response to a failed applyLog/applyTransaction operation triggers a shutdown of the Ratis server.

Instead, the desired behaviour is to stop accepting new append requests on the group. For the case of Ozone, the state machine will initiate destruction/closing of the Ratis group - this is implemented as a part of HDDS-1739.
