>
> 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
> Fix For: 2.9.0
>
> Attachments: YARN-5272.1.patch, YARN-5272.3.patch, YARN-5272.4.patch
>
>
> The fix used in YARN-3241 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.
