streaming returning 0 when submitJob fails with Exception
---------------------------------------------------------

                 Key: HADOOP-1663
                 URL: https://issues.apache.org/jira/browse/HADOOP-1663
             Project: Hadoop
          Issue Type: Bug
          Components: contrib/streaming
            Reporter: Koji Noguchi
             Fix For: 0.14.0


In streaming, if I pass an input filename that doesn't exist, 

bash-3.00$ hadoop jar hadoop-streaming.jar -mapper "/bin/cat" -reducer "/bin/cat" -input "inputfoo"
-output "output"
...
07/07/28 07:37:18 ERROR streaming.StreamJob: Error Launching job : Input path doesnt exist
: /user/knoguchi/inputfoo
bash-3.00$ echo $?
*0*


=================
Copy&Pasting Milind's comment.

its a hadoop streaming problem. See the code
below:

}catch( IOException ioe){
	LOG.error("Error Launching job : " + ioe.getMessage());
      }
      finally {
      if (error && (running_ != null)) {
	LOG.info("killJob...");
	running_.killJob();
      }
      jc_.close();

Note that it catches exception, and does not rethrow it !!!
