> This exception is being thrown in

> apparently is being ignored, since the test completes. It seems like this
> line:
> {code:java}
> String fileLocation =
> System.getenv(UserGroupInformation.HADOOP_TOKEN_FILE_LOCATION){code}
> Is not guarded against returned null value. I don't know if that's a test or
> production code issue.
