Hive over Tez via Hive JDBC - Error - hadoop

Question

I am using Hortonworks Hadoop HDP-2.3.2.0-2950
Hive over Tez engine
Below 2 queries are from Java code.
select * from ascii -- works well
select count(*) from ascii or select count(1) from ascii -- fails with error out
My code:
package com.hadoop.hive;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
/**
*
* #author hdpadmin
*
*/
public class HiveReadJDBCMain {
private static String driverName = "org.apache.hive.jdbc.HiveDriver";
/**
* #param args
* #throws SQLException
*/
public static void main(String[] args) throws SQLException {
Connection con = null;
PreparedStatement pst = null;
ResultSet res = null;
try {
// Load Hive Driver Clazz
Class.forName(driverName);
// No username and password required.(running in a local machine)
con = DriverManager.getConnection("jdbc:hive2://localhost:10000/labs");
//Connection con = DriverManager.getConnection("jdbc:hive2://localhost:10000/labs", "<Username>", "<Password>");
String tableName = "ascii";
// select * query
String sql = "select * from " + tableName;
System.out.println("Select Query Running: " + sql);
pst = con.prepareStatement(sql);
res = pst.executeQuery();
while (res.next()) {
System.out.println(String.valueOf(res.getInt(1)) + "\t" + res.getString(2));
}
pst.close();
res.close();
// regular hive query
sql = "select count(*) from " + tableName;
System.out.println("Count Query Running: " + sql);
pst = con.prepareStatement(sql);
res = pst.executeQuery();
while (res.next()) {
System.out.println(res.getString(1));
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
System.exit(1);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
} finally {
res.close();
pst.close();
con.close();
}
}
}
Error
java.sql.SQLException: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.tez.TezTask

Answer 1

Yes i have fixed by passing the below connection objects with my user name
Thanks.... :)
con = DriverManager.getConnection("jdbc:hive2://localhost:10000/labs", "hdpadmin","");

Answer 2

i also fixed by passing username in connection string . Thanks :)

Answer 3

In case your using the AWS Hive JDBC to talk with a default EMR cluster the following setup in Intellij worked for me
The trick was using user hadoop
