[jira] [Created] (TEZ-3551) FrameworkClient created twice causing minor delay

Rajesh Balamohan created TEZ-3551:
-------------------------------------

             Summary: FrameworkClient created twice causing minor delay 
                 Key: TEZ-3551
                 URL: https://issues.apache.org/jira/browse/TEZ-3551
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Rajesh Balamohan
            Priority: Minor


When tez session is created, it already starts up a framework client.
https://github.com/apache/tez/blob/master/tez-api/src/main/java/org/apache/tez/client/TezClient.java#L383
https://github.com/apache/tez/blob/master/tez-api/src/main/java/org/apache/tez/dag/api/client/DAGClientImpl.java#L89

When DAG is submitted, this frameworkclient is ignored and it ends up creating a new FrameworkClient again causing around 100ms delay which becomes substantial in sub-second execution jobs.
