Summary: Optimise locking in LlapTaskSchedulerService
Key: HIVE-24537
URL: https://issues.apache.org/jira/browse/HIVE-24537
Project: Hive
Issue Type: Improvement
Components: llap
Reporter: Rajesh Balamohan

1. Read lock should suffice for "notifyStarted()".
2. Locking in "allocateTask()" can be optimised.
3. Optimize preemptTasks() & preemptTasksFromMap(). This would help in reducing
the codepath with writeLock. Currently, it iterates through all tasks.
