Subject [jira] [Commented] (YARN-7934) [GQ] Refactor preemption calculators to allow overriding for Federation Global Algos
Date Wed, 14 Feb 2018 23:39:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16364966#comment-16364966
] 

Carlo Curino commented on YARN-7934:
------------------------------------

[~leftnoteasy] the intention is to commit this directly to trunk, so we avoid churn, as the
rest of the development will continue in YARN-7402 branch. Please check it out if you can,
if none complaints and YETUS is happy, this will go straight to trunk.

> This Jira tracks minimal changes in the capacity scheduler preemption mechanics that
allow for sub-classing and overriding of certain behaviors, which we use to implement federation
global algorithms, e.g., in YARN-7403.
