Subject [jira] [Created] (HADOOP-8270) hadoop-daemon.sh stop action is not LSB compliant
Date Wed, 11 Apr 2012 23:19:17 GMT
hadoop-daemon.sh stop action is not LSB compliant
-------------------------------------------------

                 Key: HADOOP-8270
                 URL: https://issues.apache.org/jira/browse/HADOOP-8270
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.23.1
            Reporter: Roman Shaposhnik
            Assignee: Roman Shaposhnik
             Fix For: 2.0.0


The following bit of code from hadoop-daemon.sh is not LSB compliant, since
according to http://refspecs.linuxbase.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html
a stop action on an already stopped service should return 0.

 (stop)

    if [ -f $pid ]; then
      if kill -0 `cat $pid` > /dev/null 2>&1; then
        echo stopping $command
        kill `cat $pid`
      else
        echo no $command to stop
        exit 1
      fi
    else
      echo no $command to stop
      exit 1
    fi
    ;;
