Subject [jira] [Created] (MAPREDUCE-2415) Distribute TaskTracker userlogs onto multiple disks
Date Fri, 01 Apr 2011 08:04:05 GMT
Distribute TaskTracker userlogs onto multiple disks
---------------------------------------------------

                 Key: MAPREDUCE-2415
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2415
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: task-controller, tasktracker
    Affects Versions: 0.20.204.0
            Reporter: Bharath Mundlapudi
            Assignee: Bharath Mundlapudi
             Fix For: 0.20.204.0


Currently, userlogs directory in TaskTracker is placed under hadoop.log.dir like <hadoop.log.dir>/userlogs.
I am proposing to spread these userlogs onto multiple configured mapred.local.dirs to strengthen
TaskTracker reliability w.r.t disk failures.
