Subject [jira] Created: (HBASE-1114) Weird NPEs compacting
Date Fri, 09 Jan 2009 19:53:59 GMT
Weird NPEs compacting
---------------------

                 Key: HBASE-1114
                 URL: https://issues.apache.org/jira/browse/HBASE-1114
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack


Over on apurtell cluster, hbase TRUNK on hadoop 0.18.0 branch, see below.

They are weird because first would seem to be an empty fileystem data member and the second's
line number is start of the method and even then, we check for null everywhere first before
doing stuff in here (because of Erik Holstad experience in past).
