Date Wed, 17 Apr 2013 22:53:19 GMT

     [ https://issues.apache.org/jira/browse/YARN-482?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated YARN-482:
----------------------------------

    Attachment: yarn-482.patch

Uploading new patch with tests, it also moves logic from ApplicableDepth in previous patches
to SchedulingPolicy itself.

Believe this patch is ready for review. Kicking Jenkins to see what it has to say.

> FS allows setting {{SchedulingMode}} for leaf queues. Extending this to non-leaf queues
allows using different kinds of fairness: e.g., root can have three child queues - fair-mem,
drf-cpu-mem, drf-cpu-disk-mem taking different number of resources into account. In turn,
this allows users to decide on the scheduling latency vs sophistication of the scheduling
mode.
