Konstantinos Karanasos updated YARN-8112:
-----------------------------------------
Description:
The min cardinality constraint is
Currently following PC doesn't work
{code:java}
-placement_spec zk=3,IN,NODE,zk
-placement_spec zk=1,IN,NODE,zk
{code}
Expectation: place 3/1 zk containers in any node of the cluster.
This is because when we do cardinality check, PC cannot be satisfied as there
is no "zk" tag placed on any node. But this is a very common user-case, hence
we need to support.
