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.
