Subject [jira] Created: (HADOOP-4053) Schedulers need to know when a job has completed
Date Tue, 02 Sep 2008 04:08:44 GMT
Schedulers need to know when a job has completed
------------------------------------------------

                 Key: HADOOP-4053
                 URL: https://issues.apache.org/jira/browse/HADOOP-4053
             Project: Hadoop Core
          Issue Type: Improvement
            Reporter: Vivek Ratan


The JobInProgressListener interface is used by the framework to notify Schedulers of when
jobs are added, removed, or updated. Right now, there is no way for the Scheduler to know
that a job has completed. jobRemoved() is called when a job is retired, which can happen many
hours after a job is actually completed. jobUpdated() is called when a job's priority is changed.
We need to notify a listener when a job has completed (either successfully, or has failed
or been killed).
