Subject [jira] [Commented] (YARN-5185) StageAllocaterGreedyRLE: NPE in corner case
Date Wed, 01 Jun 2016 13:16:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-5185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15310278#comment-15310278

Arun Suresh commented on YARN-5185:

[~curino], The patch looks pretty straightforward.
Is it possible to add an explicit testcase for this ? or are you saying that the tests in
YARN-5165/YARN-5164 will fail without this ? (in which case don't you think you should probably
merge this with the YARN-5165 patch ?)

> If the plan has only one interval, and the reservation exactly overlap we will have a
null from partialMap.higherKey() that we should guard against.
