It provides high throughput access to application data and is suitable for applications that have large data sets. The main goal of this tutorial is to get a simple Hadoop installation up and. Command Line is one of the simplest interface to Hadoop Distributed File System. Below are the basic HDFS File System Commands which are similar to UNIX file system commands. Once the hadoop daemons are started running, HDFS file system is ready and file system operations like creating directories, moving files, deleting files, reading files and listing directories Object java.net.URL is used for reading contents of a file.To begin with, we need to make Java recognize Hadoop's hdfs URL scheme. This is done by calling setURLStreamHandlerFactory method on URL object and an instance of FsUrlStreamHandlerFactory is passed to it.This method needs to be executed only once per JVM, hence it is enclosed in a static block
