Subject [jira] [Commented] (YARN-7541) Node updates don't update the maximum cluster capability for resources other than CPU and memory
Date Fri, 01 Dec 2017 13:52:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7541?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16274425#comment-16274425
] 

Jason Lowe commented on YARN-7541:
----------------------------------

Despite TestPBImplRecords being in the org.apache.hadoop.yarn.api package, it is in the hadoop-yarn-common
Maven project which this patch didn't touch.  The QA bot only runs tests in the projects touched
by the patch.  Looks like TestPBImplRecords is testing some records which are not in the api
project and therefore can't be moved as-is there.  Would be nice if this were split into multiple
tests, one per Maven project to tests the PBImpl classes in that project.

> When I submit an MR job that asks for too much memory or CPU for the map or reduce, the
AM will fail because it recognizes that the request is too large.  With any other resources,
however, the resource requests will instead be made and remain pending forever.  Looks like
we forgot to update the code that tracks the maximum container allocation in {{ClusterNodeTracker}}.
