---------------------------------
Thanks, [~djp] and [~ste...@apache.org] for the review.
Attached a new patch to add more documentations and use Time.monotonicNow()
instead of System.currentTimeMillis()

> We have seen TimerTasks leak which could cause application server done (such
> as oozie server done due to too many active threads)
> Although we have fixed some potentially leak situations in upper application
> level, such as
> https://issues.apache.org/jira/browse/MAPREDUCE-6618
> https://issues.apache.org/jira/browse/MAPREDUCE-6621, we still can not
> guarantee that we fixed the issue.
