Format the namenode

1. Open a new Cygwin window.
2. Execute the following commands:
   cd hadoop-0.19.1
   mkdir logs
   bin/hadoop namenode -format
   
   
   
   Format the namenode
3. The last command will run for some time and produce output similar to that shown below:
   
   Hadoop Distributed File System created.
   Now that the filesystem has been created you can proceed to the next step.
