[jira] Created: (HADOOP-4306) The temporary disk space limits should not skip jobs

The temporary disk space limits should not skip jobs
----------------------------------------------------

                 Key: HADOOP-4306
                 URL: https://issues.apache.org/jira/browse/HADOOP-4306
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Owen O'Malley


In HADOOP-657, we added disk space modeling and throttling. The scheduler currently picks the next job if there isn't enough space, which can lead to starvation of jobs that require a lot of space. It should not schedule any task if the first job can't use the space.
