[jira] [Created] (FLINK-7469) Handle slot requests occuring before RM registration completes

-----------------------------------

             Summary: Handle slot requests occuring before RM registration completes
                 Key: FLINK-7469
                 URL: https://issues.apache.org/jira/browse/FLINK-7469
             Project: Flink
          Issue Type: Sub-task
            Reporter: Eron Wright 
            Priority: Minor



Occasionally the TM-to-RM registration ask times out, causing the TM to pause registration for 10 seconds.  Meanwhile the registration may actually have succeeded in the RM.   Slot requests may then arrive at the TM while RM registration is incomplete.   

The current behavior appears to be that the TM honors the slot request.   Please determine whether this is a feature or a bug.   If a feature, maybe a slot request should implicitly complete the registration.

See attached a log showing a certain TM exhibiting the described behavior.
