      Description

      Today in https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/mob/compactions/PartitionedMobCompactor.java#L141, the select() is single-threaded. Give a large number of files, it will take several seconds to finish the job. Will see how this work can be divided and speed up the processing.
