> I created a sample UDF with Phoenix 4.4 by copying ARRAY_ELEM function
> (https://github.com/apache/phoenix/blob/master/phoenix-core/src/main/java/org/apache/phoenix/expression/function/ArrayIndexFunction.java)
> and removing the BuiltInFunction annotation
> after deploying to the server and running the following queries it throws an
> exception below
> create function UDF_ARRAY_ELEM(VARCHAR ARRAY, INTEGER) returns "VARCHAR" as
> 'com.test.ArrayIndexFunction' using jar '/tmp/udf.jar'
> CREATE TABLE TESTTABLE10(ID VARCHAR NOT NULL, NAME VARCHAR ARRAY, CITY
> VARCHAR ARRAY CONSTRAINT pk PRIMARY KEY (ID) )
> UPSERT INTO TESTTABLE10(ID,NAME,CITY) VALUES('111',

> UPSERT INTO TESTTABLE10(ID,NAME,CITY) VALUES('112',
