Subject [jira] [Created] (HBASE-14287) Bootstrapping a cluster leaves temporary WAL directory laying around
Date Fri, 21 Aug 2015 19:29:46 GMT
Lars George created HBASE-14287:
-----------------------------------

             Summary: Bootstrapping a cluster leaves temporary WAL directory laying around
                 Key: HBASE-14287
                 URL: https://issues.apache.org/jira/browse/HBASE-14287
             Project: HBase
          Issue Type: Bug
          Components: master, regionserver
    Affects Versions: 1.1.1, 1.0.2
            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.
