[jira] [Created] (HBASE-17043) parallelize select() work in mob compaction

huaxiang sun created HBASE-17043:
------------------------------------

             Summary: parallelize select() work in mob compaction
                 Key: HBASE-17043
                 URL: https://issues.apache.org/jira/browse/HBASE-17043
             Project: HBase
          Issue Type: Improvement
          Components: mob
    Affects Versions: 2.0.0
            Reporter: huaxiang sun
            Assignee: huaxiang sun
            Priority: Minor


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.
