----------------------------------------------
[~yuzhih...@gmail.com] I have attached the branch-1 patch, do I also need to
attach branch-2 patch (it's a clean cherry-pick) ?

> When backporting HBASE-18309 in HBASE-20352, the deleteFiles calls
> CleanerContext.java#getResult with a waitIfNotFinished timeout to wait for
> notification (notify) from the fs.delete file thread. there might be two
> situation need to tune the MAX_WAIT in CleanerContext or waitIfNotFinished
> when LogClearner call getResult.
> # fs.delete never complete (strange but possible), then we need to wait for
> a max of 60 seconds. here, 60 seconds might be too long
> # getResult is waiting in the period of 500 milliseconds, but the fs.delete
> has completed and setFromClear is set but yet notify(). one might want to
> tune this 500 milliseconds to 200 or less .
