-----------------------------------
There's already api. {{Admin#setCleanerChoreRunning(boolean)}}
You can turn it on or off. My vote won't change :)
> Provide CLI option to run oldwals and hfiles cleaner separately when cleaner
> chore is disabled

> Issue Type: Improvement
> Components: Admin, Client
> Affects Versions: 3.0.0, 1.4.6, 2.1.1

> There is a corner case when cleaner chore for HFiles and oldwals is disabled,
> admin/user needs to manually execute admin command {{cleaner_chore_run}} to
> clean the old HFiles and oldwals. Existing logic of {{cleaner_chore_run}} is
> to [firstly trigger the HFiles cleaner and then oldwals
> cleaner|https://github.com/taklwu/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterRpcServices.java#L1414-L1420],
> and only return succeed if both completes.
> but when running this {{cleaner_chore_run}} command, there is a potential use
> case that admin would like trigger the cleaner for only oldwals or hfiles but
> still keep the automatic cleaner chore disabled. So, this change aims to
> provide support for this corner case, and provide flexibility for those user
> with cleaner chore disabled by default to execute admin CLI 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}
