rbalamohan opened a new pull request #1431: URL: https://github.com/apache/hive/pull/1431
https://issues.apache.org/jira/browse/HIVE-24061 Changes: 1. Adjust locality delay when the task is getting scheduled. 2. Reset locality delay when all nodes in the cluster are busy and wouldn't be able to schedule tasks. 3. Optimize schedulePendingTasks to exit early, when all nodes are busy. This helps in reducing lock contention as well. Patch was tested on a medium scale cluster and observed good improvement in runtime of queries. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
