> Key: HIVE-5089
> URL: https://issues.apache.org/jira/browse/HIVE-5089
> Project: Hive
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 0.11.0
> Reporter: Julien Letrouit
> Fix For: 0.12.0
>

> This is reproducing the issue systematically:
> {noformat}
> import org.apache.hive.jdbc.HiveDriver;
> import java.sql.Connection;
> import java.sql.DriverManager;
> import java.sql.PreparedStatement;
> public class Main {
> public static void main(String[] args) throws Exception {
> DriverManager.registerDriver(new HiveDriver());
> Connection conn = DriverManager.getConnection("jdbc:hive2://someserver");
> PreparedStatement smt = conn.prepareStatement("SET hivevar:test=1");
> smt.execute(); // Exception here
> conn.close();
> }
> }
> {noformat}
> It is producing the following stacktrace:
> {noformat}

> I tried to fix it, unfortunately, the standalone server used in unit tests do
> not reproduce the issue. The following test added to TestJdbcDriver2 is
> passing:
> {noformat}
> public void testNonQueryPrepareStatement() throws Exception {
> try {
> PreparedStatement ps = con.prepareStatement("SET hivevar:test=1");
> boolean hasResultSet = ps.execute();
> assertTrue(hasResultSet);
> ps.close();
> } catch (Exception e) {
> e.printStackTrace();
> fail(e.toString());
> }
> }
> {noformat}
> Any guidance on how to reproduce it in tests would be appreciated.
> Impact: the data analysis tools we are using are performing
> PreparedStatements. The use of custom UDF is forcing us to add 'ADD JAR ...'
> and 'CREATE TEMPORARY FUNCTION ...' statement to our query. Those statements
> are failing when executed as PreparedStatements.
