Hi Swapna, We don't support custom aggregate functions, only scalar functions (see PHOENIX-2069). For a custom aggregate function, you'd need to add them to phoenix-core and rebuild the jar. We're open to adding them to the code base if they're general enough. That's how FIRST_VALUE, LAST_VALUE, and NTH_VALUE made it in. Thanks, James
