Subject [jira] Created: (HADOOP-52) mapred input and output dirs must be absolute
Date Tue, 21 Feb 2006 22:38:34 GMT
mapred input and output dirs must be absolute

         Key: HADOOP-52
         URL: http://issues.apache.org/jira/browse/HADOOP-52
     Project: Hadoop
        Type: Bug
  Components: mapred  
    Versions: 0.1    
    Reporter: Doug Cutting
     Fix For: 0.1

DFS converts relative pathnames to be under /user/$USER.  But MapReduce jobs may be submitted
by a different user than is running the jobtracker and tasktracker.  Thus relative paths must
be resolved before a job is submitted, so that only absolute paths are seen on the job tracker
and tasktracker.  I think the simplest way to fix this is to make JobConf.setInputDir(), setOutputDir(),
etc. resolve relative pathnames.
