Seems like you would want the results as:
7
3
Here is one way to get the maximum value for a collection of columns with a
case statement.
(this not done in Hive but hive case statements should work same way)
## data in table xyz
select * from xyz ;
c1 | c2 | c3
++
2 | 1 | 3
3

can be able to learn about writing the UDF?
Thanks!

Hi Sachin
AFAIK There isn't one at the moment. But you can easily achieve this using a
