Hadoop daemon does not clean up pid file upon normal shutdown
-------------------------------------------------------------

                 Key: HADOOP-7586
                 URL: https://issues.apache.org/jira/browse/HADOOP-7586
             Project: Hadoop Common
          Issue Type: Improvement
          Components: scripts
    Affects Versions: 0.22.0, 0.23.0
         Environment: Linux
            Reporter: Joep Rottinghuis
            Assignee: Joep Rottinghuis
            Priority: Minor


hadoop-daemon.sh script created pid files on when namenode, jobtrackers, etc. deamons are
started.
When the deamon is stopped in a regular manner through the stop script, it should clean up
the pid file to indicate normal controlled exit.

Presence of a pid without running corresponding process would then indicated abnormal end
of the process.
