Konstantinos Karanasos commented on YARN-6592:
----------------------------------------------
Hi [~cheersyang], indeed in our constraints API, we allow constraints on node
attributes. For such constraints to be enforceable, YARN-3409 has to be done
first.
However, the present JIRA has a broader scope, as its primary focus is on
affinity/anti-affinity/cardinality constraints between containers. For those
constraints, YARN-3409 is not required.
