> 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.
