A Hive Thriftserver example

A hive Thriftserver example.(hands on lab)

-----------------------------------------
Create java file in eclipse with name
The necessary jar files go to $HIVE_HOME/lib and search for libraries  and add to the below program .Slf4j-api-1.6.1.jar
--go to $HADOOP_HOME   search for necessary libraries and add them too.
________________________
ThriftHive.java(add all the jar in the build configuration step to the program)
--------------------------
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.DriverManager;
 
public class HiveJdbcClient {
  private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver";
 
  public static void main(String[] args) throws SQLException {
    try {
      Class.forName(driverName);
     System.out.println("try block");
    } catch (ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      System.exit(1);
    }
    Connection con = DriverManager.getConnection("jdbc:hive://localhost:10000/default", "", "");
    Statement stmt = con.createStatement();
    String tableName = "test";
    stmt.executeQuery("drop table " + tableName);
    ResultSet res = stmt.executeQuery("create table " + tableName + " (key int, value string)");
    // show tables
    String sql = "show tables '" + tableName + "'";
    System.out.println("Running: " + sql);
    res = stmt.executeQuery(sql);
    if (res.next()) {
      System.out.println(res.getString(1));
    }
    // describe table
    sql = "describe " + tableName;
    System.out.println("Running: " + sql);
    res = stmt.executeQuery(sql);
    while (res.next()) {
      System.out.println(res.getString(1) + "\t" + res.getString(2));
    }
     
  }
}

----------------------------------
Go to $HIVE_HOME/bin directory

To start the thrift server please type the below command:
$HIVE_HOME/bin>hive --service hiveserver
-------------
Go to eclipse :
After adding all the Jars we need to run the Java application and we will get the output
________
For every query hard coded in the java code in the eclipse there will be one Ok displayed on output screen.
