> We are caching the requests in the RetryCache once we receive those. There is a chance that the request fails due to the leader change. In this case, the request would fail, and it would stay in the RetryCache with the failure. As a result, if the app is relying on the RetryCache, it might continuously fail the request during the retries.  See HDDS-13621 as an example. 
> The solution should be straightforward. If we fail the request after we've started processing it but before we put it to the log file, we should remove it from the RetryCache.
