Custom aggregation UDFs in phoenix

Hi Team,

Wanted to know what is a good way to add custom aggregation UDFs in
phoenix.

I want to implement an aggregate function that will based on input either
do a last_value aggregation or a combination of last_value followed by sum
aggregations.

It seems from https://issues.apache.org/jira/browse/PHOENIX-2069 that this
is not yet supported out of the box.

Thanks in advance,
Abhishek
