Unable to establish a JDBC connection to Hive from

I am trying to establish a JDBC connection to Hive so that I can view and create tables and query Hive tables from Eclipse. I used HiveClient sample code: https://cwiki.apache.org/confluence/display/Hive/HiveClient Then I added all the required jars to the java build path inside eclipse and started Hive Thrift Server. Port 10000 is listening. I am using Cloudera QuickstartVM 4.6.1 and the eclipse that comes with it. Here's the error that I get in the IDE when I try to run the code.

Exception in thread "main" java.sql.SQLException: org.apache.thrift.transport.TTransportException: java.net.SocketException: Connection reset
    at org.apache.hadoop.hive.jdbc.HiveStatement.executeQuery(HiveStatement.java:191)
    at org.apache.hadoop.hive.jdbc.HiveStatement.execute(HiveStatement.java:127)

    at java.sql.DriverManager.getConnection(DriverManager.java:582)
    at java.sql.DriverManager.getConnection(DriverManager.java:185)
    at jdbc.Hive.main(Hive.java:24)

When I try connecting to Hive using beeline, I get the same error. However, when I eliminate the host name and port from the !connect command it works with the following error:

beeline> !connect jdbc:hive:// "" ""                 
scan complete in 4ms
Connecting to jdbc:hive://

What am I missing here!?

You have 2 options to connect hiveserver using jdbc

Option 1 : Hiveserver2

You are trying to connect hiveserver2, hiveserver version in cloudera manager is hivesever2, which is more secure than hiveserver. JDBC code you are using is hiveserver,Use the following code snippet for hiveserver2

Class.forName("org.apache.hive.jdbc.HiveDriver");
Connection con = DriverManager.getConnection("jdbc:hive2://localhost:10000/default", "hive", "");
Statement stmt = con.createStatement();
String tableName = "testHiveDriverTable";
stmt.execute("drop table if exists " + tableName);
stmt.execute("create table " + tableName + " (key int, value string)");
String sql = "show tables '" + tableName + "'";

If you look at the connection string, can see the hiveserver version 2(jdbc:hive2://localhost:10000/default", "", ""), second and third arguments are username and password, by default keep it empty string "".

For executing this program add hiveserver2 specific libraries.

Instead of writing your own programs for checking hiveserver2 jdbc connection, beeline hive client can be used as follows

> [testuser02@Abcd-Host1 ~]$ beeline

> beeline> !connect jdbc:hive2://Abcd-Host1:10000/default "" "" ""
> 
> 0: jdbc:hive2://Abcd-Host1:10000/default> show tables;

+------------+
|  tab_name  |
+------------+
| sample_07  |
| sample_08  |
| test1      |
+------------+
3 rows selected (0.334 seconds)

Options 2: Hiveserver1

If you want to make use of your existing code(code for hiveserver1), which you are having https://cwiki.apache.org/confluence/display/Hive/HiveClient. You got to start a new hiveserver in your userspace in another port. Use the following command to start a hiveserver in a given port

nohup hive --service hiveserver -p 10001 &

Now change the port number to 10001 in jdbc connection and run it.
