Impala odbc driver - querying schema

[#1]

Can anyone help me to understand what are the values I have to pass to describe the columns of a table

var con = new OdbcConnection(constring);

con.OpenAsync();

var result = con.GetSchema("Tables");

above is returning empty collection for me - Any help will be appreciated.

Thank you

Figured it out - you have to add the magic string of "impala" as the catalog name!
