Prabhu Joseph commented on YARN-9258:
-------------------------------------
[~cheersyang] Thanks for the detailed response. Have tried option #2 and found
difficult to apply each of node attribute expressions to each of constraint in
the spec. As getTargetExpressions from the PlacementConstraint is not exposed
to add new TargetExpression with node attribute.
Will work on option #1.
