--------------------------------------------
Summary: Provide CLI option to run oldwals and hfiles cleaner
separately
Key: HBASE-21011
URL: https://issues.apache.org/jira/browse/HBASE-21011
Project: HBase
Issue Type: Improvement
Components: Admin, Client
Affects Versions: 1.4.6, 3.0.0, 2.1.1
Reporter: Tak Lon (Stephen) Wu
Assignee: Tak Lon (Stephen) Wu
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
{{ hbase> cleaner_chore_run}}
{{ hbase> cleaner_chore_run 'hfiles'}}
{{ hbase> cleaner_chore_run 'oldwals'}}
