Subject [jira] Commented: (HADOOP-4996) JobControl does not report killed jobs
Date Fri, 27 Feb 2009 08:15:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12677272#action_12677272
] 

Amareshwari Sriramadasu commented on HADOOP-4996:
-------------------------------------------------

looking at JobControl code :
{code}
      running = jc.getJob(this.mapredJobID);
      if (running.isComplete()) {
        if (running.isSuccessful()) {
          this.state = Job.SUCCESS;
        } else {
          this.state = Job.FAILED;
          this.message = "Job failed!";
          try {
            running.killJob();
          } catch (IOException e1) {

          }
          try {
            this.jc.close();
          } catch (IOException e2) {

          }
        }
      }
{code}
This says that Killed jobs are informed to jobControl properly, though they are present in
failedJobs list.

Olga, what is the problem you are seeing there? Can you please elaborate? or attach a testcase
where this can be reproduced?

> After speaking with Arun and Owen, my understanding of the situation is that separate
killed job tracking was added in hadoop 18: http://issues.apache.org/jira/browse/HADOOP-3924.
> However, it does not look like this change was integrated into JobControl class. While
I have not verified this yet, it looks like, applications that use JobControl would no way
of knowing if one of the jobs was killed.
> This would be blocker for Pig to move to Hadoop 19.
