             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!" MetricsException.
