Andrew Kyle Purtell updated HBASE-25854:
----------------------------------------
Hadoop Flags: Reviewed
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Remove redundant AM in-memory state changes in CatalogJanitor
> -------------------------------------------------------------
>
> Key: HBASE-25854
> URL: https://issues.apache.org/jira/browse/HBASE-25854
> Project: HBase
> Issue Type: Sub-task
> Reporter: Andrew Kyle Purtell
> Assignee: Andrew Kyle Purtell
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3
>
>
> In CatalogJanitor we schedule GCRegionProcedure to clean up both filesystem
> and in-memory state after a split, and GCMultipleMergedRegionsProcedure to do
> the same for merges.
> Both GCRegionProcedure and GCMultipleMergedRegionsProcedure clean up
> in-memory state, but CatalogJanitor also does this redundantly just after
> scheduling the procedures.
> The cleanup should be done in only one place. Presumably we are using the
> procedures to do it in a principled way. This is least a nit, but probably a
> source of future bugs. Remove the redundancy in CatalogJanitor and fix any
> follow on issues, like test failures.
