Summary: DbTxnManger.startHeartbeat()
Key: HIVE-17341
URL: https://issues.apache.org/jira/browse/HIVE-17341
Project: Hive
Issue Type: Improvement
Components: Transactions
Reporter: Eugene Koifman
Assignee: Eugene Koifman
This sets up a fixed delay for all heartebeats. If many queries land on the
server at the same time,
they will wake up and start hearbeating at the same time causing a bottleneck.
Add some random element to heatbeat delay.
