Re: Can not connect to HAWQ(hadoop) database

Hi, are you able to share details of your solution?  Did you use Kerberos or some other authentication method with ODBC?

Were you satisfied when accessing HAWQ using ODBC? I'm looking for a more native solution (maybe based on npgsql/postgreSQL drivers) as they're usually better performance-wise. ODBC is really slow. And I even didn't get to limitations on memory size.
