Initializing the HDFS

The initialization codes used when applications are run in Linux and the codes used when applications are run in Windows are the same. The example codes are as follows:

 //initialization
 /**confLoad();

 // Creating a sample project
 HdfsExample hdfs_examples = new HdfsExample("/user/hdfs-examples", "test.txt");
 /**
  * 
  * If the application is running in the Linux OS, the path of core-site.xml, hdfs-site.xml must be modified to the absolute path of the client file in the Linux OS. 
  *
  * 
  */  
 private static void confLoad() throws IOException {
   conf = new Configuration();
   // conf file
   conf.addResource(new Path(PATH_TO_HDFS_SITE_XML));
   conf.addResource(new Path(PATH_TO_CORE_SITE_XML));
   // conf.addResource(new Path(PATH_TO_SMALL_SITE_XML));
 }

  *Create a sample project.
