Chris Nauroth commented on HDFS-9354:
-------------------------------------
Something is going wrong with the Findbugs pre-check. I'll need to follow up
on that separately.
I cannot reproduce any of the test failures, and they are not related to the
code changed in this patch.
The license check warning is a known issue with HDFS tests writing output files
outside of the Maven build root. This is tracked elsewhere.

> This negative test expect HadoopIllegalArgumentException on illegal
> configuration. It uses JUnit (expected=HadoopIllegalArgumentException.class)
> and passed fine on Linux.
> On windows, this test passes as well. But it left open handles on NN metadata
> directories used by MiniDFSCluster. As a result, quite a few of subsequent
> TestBalancer unit tests can't start MiniDFSCluster. The open handles prevents
> them from cleaning up NN metadata directories on Windows.
> This JIRA is opened to explicitly catch the Exception and ensure the test
> cluster is properly shutdown.
