    Description

      The getTables jdbc function no longer returns information when using normal JDBC table types like TABLE or VIEW. You must now use a more specific type such as MANAGED_TABLE or VIRTUAL_VIEW. An example application that will fail to return results against 0.10 is below, works without issue in 0.9. In my 0.10 test I used HS2.

      import java.sql.SQLException;
      import java.sql.Connection;
      import java.sql.ResultSet;
      import java.sql.Statement;
      import java.sql.DriverManager;
      import org.apache.hive.jdbc.HiveDriver;
      import java.sql.DatabaseMetaData;
      
      public class TestGet {
        private static String driverName = "org.apache.hive.jdbc.HiveDriver";
      
        /**
       * @param args
       * @throws SQLException
         */
        public static void main(String[] args) throws SQLException {
            try {
            Class.forName(driverName);
          } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            System.exit(1);
          }
          Connection con = DriverManager.getConnection("jdbc:hive2://hostname:10000/default");
          DatabaseMetaData dbmd = con.getMetaData();
          String[] types = {"TABLE"};
          ResultSet rs = dbmd.getTables(null, null, "%", types);
            while (rs.next()) {
              System.out.println(rs.getString("TABLE_NAME"));
            }
          }
        }
      }
