Wangda Tan created YARN-6244:
--------------------------------
Summary: Introduce AtomicResource in ResourceUsage to avoid
read-write lock.
Key: YARN-6244
URL: https://issues.apache.org/jira/browse/YARN-6244
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Wangda Tan
While doing SLS tests of YARN-5139, I found when multiple threads are doing
scheduling at the same time, read/write lock of ResourceUsage becomes
bottleneck. This could be improved.
