    Description

      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.
