[jira] [Commented] (HBASE-4740) [bulk load] the HBASE-4552 API can't tell if errors on region server is recoverable or unrecoverable error.

    [ https://issues.apache.org/jira/browse/HBASE-4740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13143642#comment-13143642 ] 

Jonathan Hsieh commented on HBASE-4740:
---------------------------------------

While reworking the tests for recoverable and simulated unrecoverable failures with the updated api, I noticed that there are some problems in the test cases I previously wrote.  There will be some significant changes with the tests in this patch as well.

Oddly I have a case where splitting was not happening in a particular test case but is in another.

> Running TestHFileOutputFormat more frequently seems to show that it has become flaky.   It is difficult to tell if this is because of a unrecoverable failure or a recoverable failure.   To make this visiable from test and for users, we need to make a change to bulkload call's interface on HRegionServer.  The change should make successful rpcs return true, recoverable failures return false, and unrecoverable failure throw an IOException.  This is an RPC change, so it would be really good to get this api right before the final 0.92 goes out.
