Subject [jira] [Commented] (YARN-7670) Modifications to the ResourceScheduler to support SchedulingRequests
Date Sat, 30 Dec 2017 01:53:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16306636#comment-16306636

Arun Suresh commented on YARN-7670:
-----------------------------------

bq. Could you help to merge the commits using git hard push since we're in branch.
YARN-6592 branch is up todate - I just rebased it with trunk and force pushed - am guessing
thats what you meant ?

bq. And also, the new added method in ResourceScheduler should not be used by a module other
than placement processor
So, my intention was that it would be a generic API - not something only the Processor can
use. My understanding from our previous discussions were that the Scheduler itself is split
into 2 phases: First is the Proposal phase and second the Commit phase. I think the API introduced
here is a formalization of the the Commit phase - no ?
Given the de-coupling, I feel we should expose the later phase as a proper public API to be
used by future features.
