Subject [jira] [Commented] (MAPREDUCE-6765) MR should not schedule container requests in cases where reducer or mapper containers demand resource larger than the maximum supported
Date Thu, 22 Sep 2016 23:22:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15514780#comment-15514780

Haibo Chen commented on MAPREDUCE-6765:
---------------------------------------

Sorry for not checking this closely. I missed the outer if statement (ResourceRequest.equals(Resources.none()).
I will upload a new patch to address the failures.

> When mapper or reducer containers request resource larger than the maxResourceRequest
in the cluster, job is to be killed. In such cases, it is unnecessary to still schedule container
requests.
