----------------------------------------
Summary: Udf's don't run execute method when using null as a
parameter.
Key: PHOENIX-4639
URL: https://issues.apache.org/jira/browse/PHOENIX-4639
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.13.2-cdh5.11.2
Environment: Centos 7 using Cloudera
Reporter: Clive Stellings
Attachments: IsNull.java
When attempting to use a UDF the code for execute never runs if the parameter
for the UDF is null. I wrote a function called isnull that and am attempting
to emulate the same function as in Mysql but when I enter null e.g.
isnull(null) it returns with an empty value and when I check if the execute
method actually runs, it never enters the method.
