Subject [jira] [Commented] (HDFS-2043) TestHFlush failing intermittently
Date Mon, 21 Mar 2016 12:54:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15204126#comment-15204126
] 

Lin Yiqun commented on HDFS-2043:
---------------------------------

As [~kihwal] pointed out, it seems to be an actual race. The two exception logs info in HDFS-10181
also indicated that the stream has been executed other operations when the {{DataStreamer.run}}
was did. Update a patch to catch the potential exceptions in stream writing operations and
add some chances to retry. Assigned this jira to me, pending jenkins.

> 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/
> https://builds.apache.org/job/PreCommit-HDFS-Build/680//testReport/
