Subject [jira] [Commented] (YARN-2497) Changes for fair scheduler to support allocate resource respect labels
Date Tue, 26 Sep 2017 18:01:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-2497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16181231#comment-16181231

Wangda Tan commented on YARN-2497:
----------------------------------

[~templedf],

bq. because it gets submitted as the label expression for the app ...
I'm not sure about this, I just checked the NODE_LABEL_EXPRESSION_NOT_SET only used by diagnostic
information such as UI / CLI / application report, etc. It is not used to do any scheduling
decisions. I agree that the naming need to be improved, so that's why I suggested above: 
- NODE_LABEL_EXPRESSION_NOT_SET => NODE_LABEL_EXPRESSION_NOT_SET_FOR_DIAGNOSTICS
- DEFAULT_NODE_LABEL_PARTITION => DEFAULT_NODE_LABEL_PARTITION_FOR_DIAGNOSTICS
- RMApp#getAppNodeLabelExpression => getAppNodeLabelExpressionForDiagnostics / getAmNodeLabelExpression
=> -
getAmNodeLabelExpressionForDiagnostics
