Ted Yu commented on HBASE-12152:
--------------------------------
In the QA run above, TestLoadIncrementalHFiles didn't hang, neither did
TestSecureLoadIncrementalHFilesSplitRecovery.
The initial subject of the JIRA was inaccurate - although
TestLoadIncrementalHFiles showed up in stack trace of hanging test, it was
TestSecureLoadIncrementalHFilesSplitRecovery that actually hung because of
userToken being null, aborting bulk load.
Since there was no timeout prior to today,
TestSecureLoadIncrementalHFilesSplitRecovery hung.
The addition of the timeout exposed the bug.
The above was result of discussion with Jeff.
