Hello,

I was wondering about a few things :

*         When I launch a query using filters on PART_DT (from the sample 
model), e.g. WHERE PART_DT='2013-12-31', I get a result through the Kylin web 
interface, whereas it gives me a mistake in Hive and Impala, indicating an 
unknown type on PART_DT. Does it mean that the data are not queried directly in 
Hive, but through a "copy".  This couls explain why the syntax "DEFAULT.<table 
name> does not work in the query editor.

*         What does happen when the Hive tables are populated ? Should I 
resynchronize the tables or not ?

*         How is the data integrity ensured ? As far as I can notice, there is 
no control on data through the model creation interface; this supposes that the 
data are initially well-formed. So how does Kylin manage this (input mistakes, 
...) ?

Thank you in advance for your help. Have a good day.

Best regards,
Jean-Luc.
