Arun Suresh commented on YARN-7822:
-----------------------------------
[~cheersyang], Thanks for working on this..
Couple of comments:
* I see a TODO stating that nested AND / OR is not supported. Given that the
the children of OR / AND can take any AbstractConstraint, it should be possible
right ?
* In your testcases, I see references to {{FiCaSchedulerNode}}. Can you replace
with SchedulerNode. We would like to keep this module as scheduler agnostic as
possible.
* Can you also add a testcase to the {{TestPlacementProcessor}} to validate an
end-2-end scenario ?
I was thinking we make changes to the DistributedShell as well. Should we do it
here ? or I am open to doing it in another JIRA.
