Subject [jira] [Commented] (YARN-4195) Support of node-labels in the ReservationSystem "Plan"
Date Fri, 18 Dec 2015 02:02:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15063282#comment-15063282
] 

Chris Douglas commented on YARN-4195:
-------------------------------------

bq. a better version of this, which uses a cool algorithm which skips the conversion to DNF

The impl is based on a SIGMOD 2010 [paper|http://dl.acm.org/citation.cfm?id=1807171] that
converts boolean expressions to intervals. I'll adapt it for Hadoop and post a patch

> As part of YARN-4193 we need to enhance the InMemoryPlan (and related classes) to track
the per-label available resources, as well as the per-label
> reservation-allocations.
