-----------------------------------
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.
