HI James/Team,
1. I'm trying to implement the generic (custom) aggregate function and
using verison: *phoenix-4.6.0-HBase-0.98 *with single-node (having hbase
and phoenix exists in one node)
When i downloaded and installed, noticed that SumAggregateFunction.class
exists in all the below mentione
Thank you James for providing the URL, I will be trying today as per the
directions.

Hi,
I found this in Phoenix UDF documentation:
- After compiling your code to a jar, you need to deploy the jar into
the HDFS. It would be better to add the jar to HDFS folder configured for
hbase.dynamic.jars.dir.
My question is, can that be any 'udf-user-specific' jar which need to b

Have you tried it yet?

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, an
Thank you James for swift response.
is the process (adding to phoenix-core and rebuild the jar) remains the
same for custom UDF's as well (like as for custom aggregate functions)?
ex: we have UDF's like UPPER, LOWER ,etc

No, custom UDFs can be added dynamically as described here:
https://phoenix.apache.org/udf.html. No need to re-build Phoenix. It's just
custom aggregates that would require rebuilding.
FYI, we have support for UPPER and LOWER already.

For custom UDF's, i understand that we can go ahead and create custom UDF
jar.
but how do we register that function?
As per the blog, i found the below lines:

Hi Swapna,
We currently don't support custom aggregate UDF, and it looks like you
found the JIRA here: PHOENIX-2069. It would be a natural extension of UDFs.
Would be great to capture your use case and requirements on the JIRA to
make sure the functionality will meet your needs.
Thanks,

Hi,
I would like to know the approach to implement and register custom
aggregate functions in Phoenix like the way we have built-in aggregate
functions like SUM, COUNT,etc
Please help.
Thanks
