Subject [jira] [Created] (MAPREDUCE-2427) JT should ensure history directory is a directory
Date Fri, 08 Apr 2011 16:56:06 GMT
JT should ensure history directory is a directory
-------------------------------------------------

                 Key: MAPREDUCE-2427
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2427
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 0.20.2
            Reporter: E. Sammer


If the JT history directory doesn't exist or isn't a directory retired job files are renamed
to a file called 'history' and eventually start overwriting each other. The JT should ensure
'history' exists and is a directory before performing the move.
