> 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.
