It's confusing with PQS in the mix :)
The original documentation meant client side (JDBC thick driver) and
server-side (HBase). With PQS in the mix, you'd need PQS and HBase (but
not client-side, guessing).

Yes, I read this. But the document says "This needs to be set at client and
server both". I've been confused - what is "client" in case of
ODBC-connection. I supposed that driver, but it seems queryserver.

Namespace mapping is something you need to enable on the server (it's off by
default).
See documentation for enabling it here:

Thanks you for response, Josh!
I got something like "Inconsistent namespace mapping properties" and
thought it was because it's impossible to set
"isNamespaceMappingEnabled" for the ODBC driver (client side). After
your explanation I understood that the "client" in this case is
queryserver but not ODBC driver. And now I need to check why queryserver
doesn't apply this property.

I'd be surprised to hear that the ODBC driver would need to know
anything about namespace-mapping.
Do you have an error? Steps to reproduce an issue which you see?
The reason I am surprised is that namespace mapping is an
implementation detail of the JDBC driver which lives inside of PQS --
*not* the ODBC driver. The trivial thing you can check would be to
validate that the hbase-site.xml which PQS references is up to date
and that PQS was restarted to pick up the newest version of
hbase-site.xml

Hi,
Is the ODBC driver from Hortonworks the only way to access Phoenix
from .NET code now?
The problem is that driver has some critical limitations - it seems,
driver doesn't support Namespace Mapping (it couldn't be able to
connect to Phoenix if phoenix.schema.isNamespaceMappingEnabled=true)
and doesn't support query hints.

Stepan.
