I think custom UDAF is the only way to achieve what you need. See existing

Hi,
My question is that does Hive able to compare same column between rows.
For instance, I have a table which contains data like below.
name, value
a, 1
a, 2
b, 1
c, 1
a, 13
b, 11
What I need is to compare 'value' columns between rows which have same 'name'.
For the name 'a'
first 'a' comes, t
Congrats! This is a big step for Hive!

Ravi,
I don’t see any other option other than doing a self join.
If not create another table with exact same data, and join both the tables with
the right join conditions to join the previous record.
