[jira] [Updated] (YARN-5994) TestCapacityScheduler.testAMLimitUsage
fails intermittently

Attachment: org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.TestCapacityScheduler-output.txt
Uploading a log of the test failing in trunk. This is a smaller race condition that I haven't seen fail on an unloaded machine. But we've seen it internally twice in the last month or so. The way I forced the test to fail was by adding a {{Thread.sleep(10000)}} immediately before {{amResourceLimit}} is set.
