Hi,

This is Kumar, and this is my first question in this group.


I have a requirement to implement ROW_NUMBER() from Teradata in Hive where 
partitioning happens on multiple columns along with multiple column ordering. 
It can be easily implemented in Hadoop MR, but I have to do in Hive. By doing 
in UDF can assign same rank to grouping key considering dataset is small, but 
ordering need to be done in prior step.
Can we do this in lot simpler way? 


Thanks in advance.


Regards,
Kumar
