[jira] [Commented] (HBASE-17534) SecureBulkLoadClient squashes DoNotRetryIOExceptions from the server

["Sean Busbey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-17534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15985698#comment-15985698 ] 

Sean Busbey commented on HBASE-17534:
-------------------------------------

+1 on the branch-1 version.

It looks like the same issue is present in master, could you make a version of the patch for that branch? I tried making a straightforward update that handled the move to the {{hbase-endpoint}} module, but it looks like something else must have changed.

> 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.
