Kevin Wilfong commented on HIVE-3796:
-------------------------------------
Updated test cases. The problem was worse than I'd thought. Because it turns of
merging using configs, and never turns it back on, it remains off for future
queries run in the same session. This means that the plans for some tests now
include merges where they did not previously.
My original full test run passed because of the issues with ptesting.
