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
> Changes for fair scheduler to support allocate resource respect labels
