Subject [jira] Updated: (HADOOP-4261) Jobs failing in the init stage will never cleanup
Date Mon, 29 Sep 2008 11:40:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amareshwari Sriramadasu updated HADOOP-4261:
--------------------------------------------

    Attachment: patch-4261.txt

Modified TestJobTrackerRestart to test setuptask Reports. 
Modified ObtainSetup/CleanupTask to use addRunningTaskToTIP()
Changed canLaunchSetupTask's implementation as suggested by Amar

bq. It would make more sense to call the job run-state as SETUP when logInited() is invoked
This would not be in consistent with JobStatus. Adding SETUP as JobStatus is not necessary.

bq.I dont see any code that deals with setup task in job-recovery i.e recovery-manager
There is no specific change required. Change in checkAndInit method will do.

> Pre HADOOP-3150, if the job fails in the init stage, {{job.kill()}} was called. This
used to make sure that the job was cleaned up w.r.t 
> - staus set to KILLED/FAILED
> - job files from the system dir are deleted
> - closing of job history files
> - making jobtracker aware of this through {{jobTracker.finalizeJob()}}
> - cleaning up the data structures via {{JobInProgress.garbageCollect()}}
> Now if the job fails in the init stage, {{job.fail()}} is called which doesnt do the
cleanup. HADOOP-3150 introduces cleanup tasks which are launched once the job completes i.e
killed/failed/succeeded.  Jobtracker will never consider this job for scheduling as the job
will be in the {{PREP}} state forever.
