+Detail for Marionette Collective message PLMC26
+===========================================
+
+Example Message
+---------------
+
+ Functions supplied to aggregate should be a hash
+
+Additional Information
+----------------------
+
+Internally when MCollective parse the DDL it converts the aggregate functions into a hash with the function name and any arguments.
+
+This error indicates that the internal translation failed, this is a critical error and would probably indicate a structure problem in your DDL or a bug in MCollective
