Some feedback on connecting to Apache Hive with MetaModel-jdbc
Hi guys,
On the DataCleaner forum we got some very nice feedback on a user's attempt
to connect to Apache Hive using MetaModel-JDBC [1].
To me it looks like that the "only" thing that's really going wrong is that
getIndexes() in JDBC does not work with their driver. I am thinking that we
should maybe make our JDBC module fault tolerant in this call - maybe
databases cannot expose index information and their drivers therefore throw
an exception here. But that's IMO not really a blocker for MetaModel (just
a bit less metadata available). We should maybe then not throw any
exceptions?

I did. But this subject was about applying the (otherwise fully working)
JDBC module to a Apache Hive database (Hive has a JDBC driver).

Hi Kasper,
Yes, in fact we are using the JDBC module within our app. I was asking
about the other way around, I thought you develop a first draft of it and
it was not ready to use yet.
Kind regards,
Alberto

Hi Alberto,
Well that's actually something quite different. We do have a JDBC module in
MetaModel which works fine - allowing you to use a relational/JDBC database
with MM. The module I think you're referring to is the other way around -
to expose a MetaModel DataContext as something that you can connect to with
JDBC.
BR,

Hi all,
Kasper I thought that the JDBC MM driver was in a very early stage ¿?
Kind regards,
