Navis updated HIVE-4573:
------------------------
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.
{code}
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"));
}
}
}
}
{code}
