Hudáky Márton Gyula created YARN-10329:
------------------------------------------
Summary: Flaky test cases in Fair Scheduler
Key: YARN-10329
URL: https://issues.apache.org/jira/browse/YARN-10329
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Hudáky Márton Gyula
The following 2 test cases are failing on unrelated patches very often:
hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairScheduler
hadoop.yarn.server.resourcemanager.scheduler.fair.TestFairSchedulerPreemption
Here is an example of failures
