Subject [jira] Updated: (HADOOP-4428) Job Priorities are not handled properly
Date Mon, 17 Nov 2008 05:18:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4428?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hemanth Yamijala updated HADOOP-4428:
-------------------------------------

    Resolution: Duplicate
        Status: Resolved  (was: Patch Available)

As per discussions that have happened on this issue, there are two separate issues identified:

- Tasks get initialized without a limit on the count initialized at a given point.
- Jobs are run out of priority order.

HADOOP-4513 moves task initialization in the capacity scheduler to a separate thread. As part
of that issue, we are working on limits to control the count.
HADOOP-4471 sorts jobs in the running queue as well. Hence, jobs are now sorted in priority
order everywhere.

In other words, the two identified issues are resolved if both the above JIRAs are fixed.
Hence, I am closing this issue as a duplicate.
