With streaming, UDF or UDTFs you would get almost any kind of control flow
you want without having those features implemented in Hive proper. For udf,
udaf or udtf you use java for implementation. In streaming you can use any
language of your choice. Not sure if this addresses stuff?

Hi experts,
I got to know that hive has no stored procedures.but this can be done in
Hive with the help of streaming and functions.Is there any way to
implement *Declare,Conditional handling statements,Control statements* in
hive.As of now i'm looking into Hive UDF's and some stored procedures in
MySQL.Trying to figure out whether it will help me in implementing the same
in Hive.

If anyone tried or implemented the above then please share with me.

Thanks & Regards,
