-----------------------------------

             Summary: Add mechanism to control hbase cleaner behavior
                 Key: HBASE-17280
                 URL: https://issues.apache.org/jira/browse/HBASE-17280
             Project: HBase
          Issue Type: Improvement
          Components: Client, hbase, shell
    Affects Versions: 1.2.0, 2.0.0
            Reporter: Ajay Jadhav
            Priority: Minor
             Fix For: 2.0.0, 1.2.0


Cleaner is used to get rid of archived HFiles and old WALs in HBase.
In the case of heavy workload, cleaner can affect query performance by creating a lot of connections
to perform costly reads/ writes against underlying filesystem.

This patch allows the user to control HBase cleaner behavior by providing shell commands to
enable/ disable and manually run it.
