Takuya Kitazawa updated HIVEMALL-90:
------------------------------------
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.
