Subject Trying to run simple Java script againt Hive in Eclipse on Windows
Date Thu, 07 Jan 2016 10:37:08 GMT
Hi Java Gurus,

 

 

I have written a simple Java program that works fine when I run it on Linux
as hduser (the OS owner for Hadoop, Hive etc)

 

When I create a project in Eclipse on Windows and have copied over
$HIVE_HOME/lib from Linux to Windows and added as external libraries, the
execution fails with the following error

 

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.

Exception in thread "main" java.lang.NoClassDefFoundError:

Appreciate any input

 

 

 

The code is as follows

 

package hivework;

  public static void main(String[] args) throws SQLException {

    boolean confirm = false;

    _username = "hduser";

    _password = "hduser";

    int status = 0;

    String query = null;

    String TableName = null;

    Connection _con = null;

    try {

      Class.forName(driverName);

    } catch (ClassNotFoundException e) {

      // TODO Auto-generated catch block

      e.printStackTrace();

      System.exit(1);

    }

    ResultSet rs = null;

    _con = DriverManager.getConnection(_hiveserver+_database, _username,
_password);

    Statement statement = _con.createStatement();

    query = "show tables";

    rs = statement.executeQuery(query);

    rs = statement.getResultSet();

    //ResultSetMetaData rsmd = rs.getMetaData ();

    System.out.println("Running: " + query);

    while (rs.next()) {

    System.out.println(rs.getString(1));

  }

    query = "show databases";

    rs = statement.executeQuery(query);

    rs = statement.getResultSet();

    System.out.println("Running: " + query);

    while (rs.next())

    {

      System.out.println(rs.getString(1));

    }

// let us do some DML

//

   try

   {

    TableName = "michboy";

    query = "drop table if exists " + TableName;

    System.out.println("Running: " + query);

    statement.executeUpdate(query);

    query = "create table " + TableName + "(col1 int, col2 varchar(30))";

    System.out.println("Running: " + query);

    statement.executeUpdate(query);

    query = "show tables";

    rs = statement.executeQuery(query);

    rs = statement.getResultSet();

    System.out.println("Running: " + query);

    while (rs.next())

    {

      System.out.println(rs.getString(1));

    }

    query = "desc michboy";

    rs = statement.executeQuery(query);

    rs = statement.getResultSet();

    System.out.println("\n Running: " + query+ "\n");

    while (rs.next())

    {

      System.out.println(rs.getString(1));

    }

    query = "select * from michboy";

    rs = statement.executeQuery(query);

    rs = statement.getResultSet();

    System.out.println("Running: " + query);

    while (rs.next())

    {

      System.out.println(rs.getString(1));

    }

//

   }catch(SQLException se){

      //Handle errors for JDBC

      se.printStackTrace();

   }catch(Exception e){

      //Handle errors for Class.forName

      e.printStackTrace();

   }

 

}//end main

}//HiveJdbcClient
