Getting Index out of bound while executing statement

[Nikunj Thakkar]

Hi,


I'm executing simple statement in current master branch of drill. Getting
following exceptions:

java.sql.SQLException: Unexpected RuntimeException:

Code:

Class.forName("org.apache.drill.jdbc.Driver");
Connection connection =
DriverManager.getConnection("jdbc:drill:zk=<my_zookepper_url>:2181/drill/drillbits1");
Statement st = connection.createStatement();
ResultSet rs = st.executeQuery("select * from hdfs.`/test/example.csv`
limit 10");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Any help would be appreciated.

Thanks,
Nikunj
