      Description

      HADOOP-3864 made the following changes to JobTracker.killJob()

         public synchronized void killJob(JobID jobid) {
           JobInProgress job = jobs.get(jobid);
      -    job.kill();
      +    if (job.inited()) {
      +      job.kill();
      +    }
         }
      

      This is a bug as a job will not get killed if its not yet initialized.

          As suggested by Arun/Sameer, moved the flags to a private class JobInitKillStatus.
          I have retained initStarted for the reason that schedulers may take time to get to initTasks for the job if there are lot of jobs or scheduler threads are busy with doing init of other jobs.

          Sameer has a good point that since the schedulers may delay initializing jobs for an arbitrary length of time, we should probably kill jobs before they get to init.

          the current patch is already doing it. As far I understand, Arun and Sameer have suggested to move those flags to a class.

          It would be far better if we could always make the kill method do the kill and block if it is in the middle of initialization.

          Agreed, that would be ideal and cleaner as well (just make kill as synchronized). But we are trying to deal with the problem of jobtracker locking - see HADOOP-3864. Currently during the kill job, the jobtracker is locked and we can't afford to block the kill job if its in the middle of initTasks().
          HADOOP-869 is seemingly becoming more important.

          You need to explicitly terminateJob to make sure all of the tasks are marked as killed.

          When is a JobInProgress created, as soon as a job is submitted or when it is considered for running??

          If the former then having a 'initStarted' flag would make sense. Because if (!initStarted) then it could be a long time before a job is considered for running and it'll hang around in the queue, killed but not purged. If so, I think this patch does the right thing.

          Regardless of whether or not we need an initStarted flag, I think it's cleaner to create a JobInitKillStatus class with the flags as members and synchronizie around an instance of this class.

          As far as this patch goes, I think

          synchronized(tasksInited){
            if(jobKilled) {
              terminateJob(JobStatus.KILLED);
              return;
            }
            initStarted = true;
          }
          

          should just be

          synchronized(tasksInited){
            if(jobKilled) {
              return;
            }
            initStarted = true;
          }

          Ok, I had a long discussion with Sameer and Owen about this and here is a slightly modfied approach we feel is slightly more maintainable:

          1. Introduce a new job-status class with 2 booleans: killJob and initTasks.
          2. JobInProgress.kill should synchronize on the new status object, set the 'killJob' boolean to true (via a setter) and then check the 'initTasks' and call terminate if necessary while holding the lock on the status object.
          3. Similarly JobInProgress.initTasks should synchronize on the status object at the end (not at the beginning, there-by eliminating the need for the 'initStarted' flag) and call terminate if necessary while holding the lock on the status object.

          Basically, the proposal is to keep a single object which tracks killJob and initTasks simultaneously rather than relying on too many pieces.

          Thoughts?

          kill() in JobInProgress has been made reentrant.
          Informing clients about the already issued kill is non-trivial as it will require interface change. Also, we don't do this for others commands like kill task. So I think it shouldn't be done as part of this jira.

          JobInProgess.kill() should be made re-entrant. We need this as some schedulers may wish to kill jobs that violate certain resource requirements and we don't want to waste cycles on terminating a job that is already killed.

          Additionally, we will somehow need to inform job-clients which try to terminate jobs for which a kill has already been issued. Currently, on re-kill attempts, it just keeps saying "job is killed successfully".

          +1 for not exposing 2 apis.

          This patch should also have a fix for JobInProgress.kill() so that calling this on an uninitialized job kills the job completely.

          This should have been taken care in HADOOP-4261. The task-initializer should call job.kill() which should do one of the 3 things

          • garbageCollect() is the job has not started (HADOOP-4261)
          • mark for kill if the job is in init (this issue)
          • mark for cleanup if the job is running

          Ideally there should be only one api to kill a job (say killJob()) which internally does the switching. Having 2 apis (killJob() and terminateJob()) is confusing.

          This will be fixed in HADOOP-4261

          HADOOP-4261 didn't solve this issue, but it did facilitate a work around by making JobInProgress.terminateJob() package private. So, callers that wish to kill a job should do something like this:

          if (job.inited()) {
            job.kill();
          } else {
            job.terminateJob(JobStatus.KILLED);
          }
          

          It will be good if we can wrap this into a single useful method for easy use.

          At present, calling JIP.kill() will just mark the job for killing, but job is truly not killed completely. A job is completely killed only when JIP.terminateJob()) is called on it, which does things like logging to JobHistory and marking JobStatus as killed. Currently, this method isn't called until a clean-up task is scheduled and runs to completion, but for uninitialized jobs there are no clean-up tasks and so job-kill remains incomplete for ever.

          This will be fixed in HADOOP-4261
