Jason Lowe commented on HADOOP-15755:
-------------------------------------
Thanks for the report and patch! Fix looks fine. It could use
Collections.emptyList but that's not a must-fix.
Would you mind adding a unit test? It's trivial in this case since the test
just needs to invoke the method with a null args parameter. That way if
someone later refactors the method a test will verify this doesn't regress.
