----------------------------------

             Summary: UDF documentation doesn't get people where they need to be
                 Key: DRILL-3516
                 URL: https://issues.apache.org/jira/browse/DRILL-3516
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Ted Dunning


The UDF documentation on the web side rooted at http://drill.apache.org/docs/develop-custom-functions/
does not describe the high level process for how UDF's are used, nor does it describe why
simple things like toString can't work on *Holder data structures.

This leads to huge confusion and frustration on the part of potentially contributors.

Here are some pertinent threads:
