Subject [jira] [Created] (FLINK-12193) [Distributed Coordination] Send TM "can be released status" with RM heartbeat

Andrey Zagrebin created FLINK-12193:
---------------------------------------

             Summary: [Distributed Coordination] Send TM "can be released status" with RM
heartbeat
                 Key: FLINK-12193
                 URL: https://issues.apache.org/jira/browse/FLINK-12193
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
            Reporter: Andrey Zagrebin
             Fix For: 1.9.0


We introduced a conditional release of Task Executor in Resource Manager in FLINK-10941.
At the moment RM directly asks TE every release timeout whether it can be released (all
depending consumers are done). We can piggyback TE/RM heartbeats for this purpose. In this
case, we do not need additional RPC call to TE gateway and could potentially release TE quicker.
