------------------------------------------------------------
Thanks for the patch [~maniraj...@gmail.com]
Instead of having a separate {{SchedulingRequestEventAsyncThread}}, it should
be possible to just replace the default backing queue of the
schedulingThreadPool like so:
{code}
this.schedulingThreadPool = new ThreadPoolExecutor(.., priorityQueue, ..);
{code}
You might even consider using the
{{org.apache.hadoop.util.BlockingThreadPoolExecutorService}} or add a method to
create a priority backed threadpool.
