> ORC fast merge (HIVE-7509) will fail the merge task in case if any of the precondition
checks fail. Precondition check fail is good for "ALTER TABLE .. CONCATENATE" but not for
automatic trigger of merge task from conditional resolver. In case if a partition has non-compatible
ORC files for merging then the merge task should ignore it and not fail the task.
