Subject [jira] Issue Comment Edited: (HADOOP-4768) Dynamic Priority Scheduler that allows queue shares to be controlled dynamically by a currency
Date Wed, 08 Apr 2009 14:13:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4768?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12696664#action_12696664

-----------------------------------------------------------------

Fixed up scheduler to be standalone and not rely on or change capacity or fairshare schedulers.
Implemented interfaces recommended by Owen and Arun but kept them in contrib for now to avoid
changing core classes.  A new design doc is also available at: http://tycoon.hpl.hp.com/~sandholm/DynamicPriorityHadoop.pdf
