> Just wanted to check if any of you have faced this earlier. Also when I try
> to run the Custom UDAF on another server it works fine. The only difference I
> can see it that the hive version I am using on my local machine is 0.13.1
> where it is working and on the other machine it is 0.13.0 where I see the
> above mentioned error. I am not sure if this was a bug which was fixed in the
> later release but I just wanted to confirm the same.
