> Key: HBASE-30302
> URL: https://issues.apache.org/jira/browse/HBASE-30302
> Project: HBase
> Issue Type: Bug
> Components: SFT
> Affects Versions: 2.6.0, 3.0.0
> Reporter: Dong0829
> Assignee: Dong0829
> Priority: Major
>
> CatalogJanitor.cleanParent gates GCRegionProcedure on whether the daughters
> still reference the parent, and that check only ever tested
> StoreFileInfo.isReference() – never HFileLink.isHFileLink(). A daughter
> holding nothing but HFileLinks therefore reported "no references", so the
> parent was collected after the split while the daughters still depended on
> it. The daughters' links were then left dangling and the regions failed to
> open with FileNotFoundException.
>
> Reproduce:
> we can reproduce the issue using unit test like create a daughter region with
> HFileLinks, and go GC and we can see the parent was GCed
