Ashutosh Chauhan commented on HIVE-1511:
----------------------------------------
[~romixlev] Thanks for taking a look. Appreciate your continued help. The
reason I have not reported these failures on kryo list is exactly the same as
you have identified. I am not yet sure that these failures are because of bugs
in kryo. We need to do more digging at our end to validate that our usage of
Kryo is correct and the patch is correct as well.
