Lokesh Jain commented on HDDS-959:
----------------------------------
The test failures do not seem to be related. The failure in
TestKeys#testPutAndGetKeyWithDnRestart is not related because the test uses
cluster with a single datanode. Therefore there is no issue of a leader
election.
The failure in TestOzoneRpcClient is related to XceiverClientGrpc.
> KeyOutputStream should handle retry failures

> 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.
