Wilfred Spiegelenburg created YARN-5272: -------------------------------------------
Summary: FairScheduler handles "invalid" queue names inconsistently even after YARN-3241 Key: YARN-5272 URL: https://issues.apache.org/jira/browse/YARN-5272 Project: Hadoop YARN Issue Type: Bug Components: fairscheduler Affects Versions: 2.8.0 Reporter: Wilfred Spiegelenburg Assignee: Wilfred Spiegelenburg The fix used in YARN-3214 uses a the JDK trim() method to remove leading and trailing spaces. The QueueMetrics uses a guava based trim when it splits the queues. The guava based trim uses the unicode definition of a white space which is different than the java trim as can be seen [here|https://docs.google.com/a/cloudera.com/spreadsheets/d/1kq4ECwPjHX9B8QUCTPclgsDCXYaj7T-FlT4tB5q3ahk/pub] A queue name with a non-breaking white space will thus still cause the same "Metrics source XXX already exists!"
