> While writing some tests against 1.x, I noticed that what should have been a DoNotRetryIOException
sent to the client from a RegionServer was getting retried until it reached the hbase client
retries limit.
> Upon inspection, I found that the SecureBulkLoadClient was wrapping all Exceptions from
the RPC as an IOException. I believe this is creating a case where the RPC system doesn't
notice that there's a DNRIOException wrapped beneath it, thinking it's a transient error.
> This results in clients having to wait for the retry limit to be reached before they
get acknowledgement that something failed.
