[jira] [Created] (PHOENIX-2891) Support system-wide UDFs

Nick Dimiduk created PHOENIX-2891:
-------------------------------------

             Summary: Support system-wide UDFs
                 Key: PHOENIX-2891
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2891
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.4.0
            Reporter: Nick Dimiduk


Current UDF implementation requires the use of DynamicClassLoader to locate function classes. This imposes all sorts of filesystem permissions complications when running clients as non-hbase users. Some of these problems can be simplified by supporting loading classes from "standard" classloader, IE, whatever is in hbase/sqlline's classpath. Not requiring the DynamicClassLoader means those permissions issues can be avoided and better support top-down installation of UDFs (ie, via configuration management systems like chef/puppet). This will enable a simplified model of deployment for system or "site" UDFs.
