      Description

      Current implementation cannot handle some merge orders e.g.,

      {0, 2, 1}

      in case of a test case https://github.com/apache/incubator-hivemall/blob/97bc91247f1a453b6ffb49212800fa601d25c297/core/src/test/java/hivemall/evaluation/AUCUDAFTest.java#L207

      This should be refined, and AUC UDAF has to be able to compute and merge partial results in an arbitrary order.
