I don't get what the Spotbugs issue is about for the "VO_VOLATILE_INCREMENT" bug, as I'm updating the volatile field from synchroinzed methods only, which is enough to keep it thread-safe. For reference, here's the Spotbugs error reported: ``` Increment of volatile field org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.AbstractCSQueueUsageTracker.numContainers in org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.AbstractCSQueueUsageTracker.decreaseNumContainers() Bug type VO_VOLATILE_INCREMENT (click for details) In class org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.AbstractCSQueueUsageTracker In method org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.AbstractCSQueueUsageTracker.decreaseNumContainers() Field org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.AbstractCSQueueUsageTracker.numContainers At AbstractCSQueueUsageTracker.java:[line 56] ``` Also, the unit test failure is a known flaky: `"[ERROR] testAllocation[Duration 90,000,000, height 0.25, numSubmission 1, periodic 86400000)](org.apache.hadoop.yarn.server.resourcemanager.reservation.TestCapacityOverTimePolicy) Time elapsed: 0.026 s <<< FAILURE!"` - https://issues.apache.org/jira/browse/YARN-9450 - https://issues.apache.org/jira/browse/YARN-7548 -- This is an automated message from the Apache Git Service.
