> Components: Admin, Client
> Affects Versions: 1.4.6, 3.0.0, 2.1.1

>
> Existing logic of cleaner chore is first execute HFiles cleaner and then
> oldwals cleaner in a request, and only return succeed if both completes.
> There is a use case of running only oldwals cleaner because oldwals uses all
> the disk space, and running HFiles cleaner is too slow because either the
> amount of old HFiles or directories are too much. So, this change provide the
> flexibility for those disabled cleaner by default or would like to execute
> admin command to run oldwals and HFiles cleaning procedure individually.
> NOTE that we keep the default as running both of them for backward
> compatibility, e.g. the proposed admin CLI options are
> {noformat}
> hbase> cleaner_chore_run
> hbase> cleaner_chore_run 'hfiles'
> hbase> cleaner_chore_run 'oldwals'
> {noformat}
