---------------------------------------
Summary: Check that grouping column is optional for predict
functions in all modules
Key: MADLIB-1208
URL: https://issues.apache.org/jira/browse/MADLIB-1208
Project: Apache MADlib
Issue Type: Bug
Components: All Modules
Reporter: Frank McQuillan
Fix For: v1.14
Follow on from: https://issues.apache.org/jira/browse/MADLIB-1207
Check all predict functions to ensure that the grouping column is optional.
This is needed because grouping is often added in a later release and if the
predict function makes it mandatory, then you can't use your models trained
before you upgraded.
