Tak Lon (Stephen) Wu updated HBASE-21011:
-----------------------------------------
    Description: 
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}
