> Key: HBASE-30339
> URL: https://issues.apache.org/jira/browse/HBASE-30339
> Project: HBase
> Issue Type: Bug
> Components: mob
> Affects Versions: 3.0.0, 2.6.4, 2.6.5, 2.6.6, 2.6.7
> Reporter: Xiao Liu
> Assignee: Xiao Liu
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0-alpha-1, 2.7.0, 3.1.0, 3.0.1, 2.6.8
>
>
> {\{MobFileCleanupUtil}} iterates over real data regions but creates
> {\{HRegionFileSystem}} using the MOB pseudo-region. \{{StoreFileTracker}}
> therefore
> reads the wrong directory and returns no store files.
> Old store files without \{{MOB_FILE_REFS}} are missed, so cleanup may archive
> MOB
> files that are still referenced.
> Use the \{{RegionInfo}} from the current region directory when creating
> {\{HRegionFileSystem}}.
