Summary: Update guranteed capacity in ZK only when WM is enabled
Key: HIVE-23208
URL: https://issues.apache.org/jira/browse/HIVE-23208
Project: Hive
Issue Type: Improvement
Components: llap
Reporter: Rajesh Balamohan
[https://github.com/apache/hive/blob/master/llap-tez/src/java/org/apache/hadoop/hive/llap/tezplugins/LlapTaskSchedulerService.java#L1091]
Though WM is not enabled, it ends up updating ZK for every dag completion
event. For short running queries with concurrency, this ends up with lots of
calls to ZK.
It would be good to invoke this only when WM is enabled.
