[jira] [Created] (TEZ-1653) Dynamic heartbeat intervals between task and AM

Bikas Saha created TEZ-1653:
-------------------------------

             Summary: Dynamic heartbeat intervals between task and AM
                 Key: TEZ-1653
                 URL: https://issues.apache.org/jira/browse/TEZ-1653
             Project: Apache Tez
          Issue Type: Task
            Reporter: Bikas Saha


The internval is fixed now. Based on load (number of running tasks etc) the container/task heartbeat could be adjusted. The AM could return the next heartbeat interval in the response. The interval could be small when num tasks is small and large when num tasks is high. This will help with AM scalability.
