Xintong Song commented on FLINK-17976:
--------------------------------------

bq. For question #1, it is probably a bug or improvement of 
{{ActiveResourceManager}}. Currently, we decrease the pending workers after 
allocated, not TaskManager registered. So both in K8s and Yarn, we may come 
into this issue. cc [~xintongsong], i think you could give more suggestions 
here.

This is indeed a problem. I've created FLINK-18226 for tracking this.
