>                 Key: HBASE-14287
>                 URL: https://issues.apache.org/jira/browse/HBASE-14287
>             Project: HBase
>          Issue Type: Bug
>          Components: master, regionserver
>    Affects Versions: 1.0.2, 1.1.1
>            Reporter: Lars George
>            Priority: Minor
> When a new cluster is started, it creates a temporary WAL as {{hbase:meta}} is created
during bootstrapping the system. Then this log is closed before properly opened on a region
server. The temp WAL file is scheduled for removal, moved to oldWALs and eventually claimed.
Issue is that the WAL directory with the temp region is not removed. For example:
> {noformat}
> drwxr-xr-x   - hadoop hadoop          0 2015-05-28 10:21 /hbase/WALs/hregion-65589555
> {noformat}
> The directory is empty and does not harm, but on the other hand it is not needed anymore
and should be removed. Cosmetic and good housekeeping.
