> Key: HDFS-3041
> URL: https://issues.apache.org/jira/browse/HDFS-3041
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 0.23.0, 0.24.0

>
> TestHFlush.testHFlushInterrupted can fail occasionally due to a race: if a
> thread is interrupted while calling close(), then the {{finally}} clause of
> the {{close}} function sets {{closed = true}}. At this point it has enqueued
> the "end of block" packet to the DNs, but hasn't called {{completeFile}}.
> Then, if {{close}} is called again (as in the test case), it will be
> short-circuited since {{closed}} is already true. Thus {{completeFile}} never
> ends up getting called. This also means that the test can fail if the
> pipeline is running slowly, since the assertion that the file is the correct
> length won't see the last packet or two.
