Wangda Tan commented on YARN-8015:
----------------------------------
Thanks [~cheersyang], in general the patch looks good. I'm only not sure about
following logic inside reinitialize():
{code:java}
CapacitySchedulerMetrics.destroy();{code}
Reinitialize could be frequently invoked, probably we should not destroy it on
every reinitialize.

> AppPlacementAllocator currently only supports intra-app anti-affinity
> placement constraints, once YARN-8002 and YARN-8013 are resolved, it needs to
> support inter-app constraints too. Also, this may require some refactoring on
> the existing code logic. Use this JIRA to track.
