Thanks [~ljain]. The patch does not apply to trunk anymore. Can you please

> 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.
