Hive-Java JDBC连接问题

Question

I am doing a program in Java and I need to connect with a database in hive. I am using mysql as metastore. Hadoop, mysql and hive work without problem. I have created my database warehousedb and the table person inside it and also I inserted datas for the hirve console. The problem is when I intent to do the connection via JDBC with this database through my Java program. I was looked for internet and I have also put all the libraries that I have indicated.

When I execute those lines appear an exeption:

Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");
Connection co = DriverManager.getConnection("jdbc:hive://localhost:9000/warehousedb", "", "");

java.sql.SQLException: org.apache.thrift.transport.TTransportException

at connection.Conection.getHiveConnection(Conection.java:38)
at logic.Exc.main(Exc.java:19)

If I try with the hiveserver2:

Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");
Connection co = DriverManager.getConnection("jdbc:hive2://localhost:9000/warehousedb", "hive", "hive");

How can I do the connection?

Answer 1

At first Make Sure which jar (hive ) do you want .. because it has diferent versions The old verison jar is

org.apache.hadoop.hive.jdbc.HiveDriver

and the newest jar is org.apache.hive.jdbc.HiveDriver
The hiveserver2 port is 1000

for example

 Class.forName(org.apache.hive.jdbc.HiveDriver);
    Connection conn = DriverManager.getConnection(jdbc:hive2://192.168.1.1:10000/default);
