It is actually a storage related thing and is applicable to all kinds of storages, and not only HDFS. Have you ever notices that before starting to use any hard drive or flash drive etc, you need to first format it?This is required to create a proper layout(creation of blocks, tracks, sectors etc) which will be used for data storage. It's ,like buying a piece of land. You can obviously go there but in order to actually live there you have to build a house on that land. Same is the case here.Tariqhttps://www.blogger.com/profile/04031146667434394770noreply@blogger.comtag:blogger.com,1999:blog-3662395151769943880.post-56009306097304767202013-04-02T14:12:57.761+05:302013-04-02T14:12:57.761+05:30Hi Mohammad, thanks for your tutorial :)!

Apart from this you can give "Hadoop-The Definitive Guide".It's a great book.You can also visit other posts of mine.I have covered few other things as well.HTH<br />Thank you.Tariqhttps://www.blogger.com/profile/04031146667434394770noreply@blogger.comtag:blogger.com,1999:blog-3662395151769943880.post-2022156712868741882013-01-14T20:09:01.004+05:302013-01-14T20:09:01.004+05:30Thanks for providing such a wonderful tutorial.
