Pankaj Kumar commented on HBASE-22806:
--------------------------------------
Issue is applicable to branch-1 also but fix will be different as BulkReOpen
reopens the region asynchronously unlike GeneralBulkAssigner,
{code}
/**
* Reopen the regions asynchronously, so always returns true immediately.
* @return true
*/
@Override
protected boolean waitUntilDone(long timeout) {
return true;
}
{code}
To fix this problem in branch-1, we need to add region reopen completion wait
logic or disable-enable the table.
[~apurtell] Please provide your opinion.

> While deleting the CF dynamically (without disabling the table), CF dirs are
> not cleared from FS when region memstore contain entries for that CF.
> Since we delete the CF from FS first and then reopen the region, during
> reopen RS will flush the memstore content to FS. So deleted CF store will
> contain the memstore content for the deleted CF.
> So adding back same CF will have old entries.
