> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node
> Affects Versions: 0.20.204.0, 0.20.205.0
> Reporter: Bharath Mundlapudi
> Assignee: Bharath Mundlapudi
> Fix For: 0.20.205.0

>
> As a part of datanode process hang, this part of code was introduced in
> 0.20.204 to clean up all the waiting threads.
> - try {
> - readPool.awaitTermination(10, TimeUnit.SECONDS);
> - } catch (InterruptedException e) {
> - LOG.info("Exception occured in doStop:" + e.getMessage());
> - }
> - readPool.shutdownNow();
> This was clearly meant for production, but all the unit tests uses
> minidfscluster and minimrcluster for shutdown which waits on this part of the
> code. Due to this, we saw increase in unit test run times. So removing this
> code.
