> TestHFlush failing intermittently
> ---------------------------------
>
> Key: HDFS-2043
> URL: https://issues.apache.org/jira/browse/HDFS-2043
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Aaron T. Myers
>
> 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/
