Lin Yiqun updated HDFS-2043:
----------------------------
Attachment: HDFS-2043.004.patch
Thanks [~iwasakims] for great analysis!

The testHFlushInterrupted expects that the second stm.close() succeeds but it
is not true. Underlying streamer thread is closed since closeThreads(true) is
called in the finally block of DFSOutputStream#closeImpl.
{quote}
This operation was added in HDFS-9812, that issue fixed the problem of streamer
threads leaking if failure happens when closing DFSOutputStream. And after
HDFS-9812 fixed, the second {{stm.close()}} will failed more frequently.
Thanks again for the comment. Post a new patch for this.

> I can't reproduce this failure reliably, but it seems like TestHFlush has
> been failing intermittently, with the frequency increasing of late.
> Note the following two pre-commit test runs from different JIRAs where
> TestHFlush seems to have failed spuriously:
> https://builds.apache.org/job/PreCommit-HDFS-Build/734//testReport/
