    Description

      As discussion in HBASE-18309, it is possible that thread flood occurs when LogCleaner and HFileCleaner start their responsibility simultaneously in HMaster, worse case would drag NameNode down which would be the most unpleasant situation.

      We shall find a way to minimize the probability of that, or the better case, avoid that happening.
