Hi guys,
I am wondering. Is there any other mailing list for hive related questions?
I feel there is not much activity on the user/dev hive mailing lists or at least not much
support in answering my questions. 

Thanks,Robert

 Hi guys,
I am wondering if it's possible to estimate the number of distinct keys and their distribution
in a way or another. 

More concretely, for every stage, it is possible to determine the number of distinct keys
and for each key the number of values  before the data is actually processed?
Thanks,Robert
