> 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.
