[jira] [Created] (HDDS-959) KeyOutputStream should handle retry failures

Lokesh Jain created HDDS-959:
--------------------------------

             Summary: KeyOutputStream should handle retry failures
                 Key: HDDS-959
                 URL: https://issues.apache.org/jira/browse/HDDS-959
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Lokesh Jain
            Assignee: Lokesh Jain


With ratis version updated to 0.4.0-a8c4ca0-SNAPSHOT, retry failures are fatal for a raft client. If an operation in raft client does not succeed after maximum number of retries(RaftRetryFailureException) all subsequent operations are failed with AlreadyClosedException. This jira aims to handle such exceptions. Since we maintain a cache for clients in XceiverClientManager, the corresponding client needs to be invalidated in the cache.
