Konstantinos Karanasos commented on YARN-8113:
----------------------------------------------
Thanks for working on this, [~cheersyang].
A couple of comments:
* I think you removed from the scheduler handler description the sentence "It
currently supports anti-affinity constraints (no affinity or cardinality)". I
thought we still do not have support inside the scheduler for that (only the
processor can do this). If this is the case, we should keep this sentence.
* Can we instead of "server" and "processor" in your AND example, use
something like storm, zk, spark? It took me a moment to understand that
processor and server are just tags.
* In the {{PlacementSpec}} description, we should add the syntax for AND and
OR.
* Minor: You can put the "Allocation tags namespace" paragraph above the
"Differences between node labels, attributes, and tags" para.
> Update placement constraints doc with application namespace and inter-app
> constraints
