> In HADOOP-11827, a producer-consumer style thread pool was introduced to parallelize
the task of listing files/directories.
> We have a use case where a distcp job is run during the commit phase of a MR2 job. However,
it was found distcp does not terminate ProducerConsumer thread pools properly. Because threads
are not terminated, those MR2 jobs never finish.
> In a more typical use case where distcp is run as a standalone job, those threads are
terminated forcefully when the java process is terminated. So these leaked threads did not
become a problem.
