Subject [jira] [Commented] (YARN-5164) CapacityOvertimePolicy does not take advantaged of plan RLE
Date Mon, 06 Jun 2016 22:12:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-5164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15317371#comment-15317371
] 

Carlo Curino commented on YARN-5164:
------------------------------------

Checkstyle and javadocs + creating patch after YARN-5165 is committed. [~chris.douglas] can
you take a look, since you are already familiar with the intended behavior of the code? Thanks.

> As a consequence small time granularities (e.g., 1 sec) and long time horizon for a reservation
(e.g., months) run rather slow (10 sec). 
> Proposed resolution is to switch to interval math in checking, similar to how YARN-4359
does for agents.
