Subject [jira] [Created] (DRILL-3520) Provide better logging around UDF loading and module loading
Date Mon, 20 Jul 2015 16:17:04 GMT
Jacques Nadeau created DRILL-3520:
-------------------------------------

             Summary: Provide better logging around UDF loading and module loading
                 Key: DRILL-3520
                 URL: https://issues.apache.org/jira/browse/DRILL-3520
             Project: Apache Drill
          Issue Type: Sub-task
            Reporter: Jacques Nadeau


When adding an extension to Drill, sometimes it is hard to know what is going on.  We should:

- improve logging so that we report at INFO level information about all the Jar files that
were included in Drill's consideration set (marked) and those that are not. (and include this
debug analysis in the documentation)
- If Drill fails to load a function, register an error function so that trying to invoke the
UDF will provide the user with information about why the function failed to load.
