I have to practise hadoop(hive,pig,sqoop,oozie,map reduce ) online for free.could anybody provide input on this?

Sure!! Just navigate over to http://hortonworks.com/products/sandbox/ to download the free Hortonworks Sandbox and to check out all the available tutorials listed there. I do assume you already know about this, so feel free to refine your question. 😉

If you can use a downloaded virtual machine, try out the "Hortonworks Sandbox" at http://hortonworks.com/downloads/#sandbox (as Lester mentioned above). This is a pre-installed single-node Hadoop cluster inside a virtual machine. You can get the sandbox for VM-Ware (commercial - but there is a free viewer) or for VirtualBox (which is free). You should be able to run this on any Windows / Mac / Linux machine so long as you have enough disk space and RAM. Similar downloads also exist for the other major distributors of Hadoop.

There are also links on the same page for accessing an online sandbox via Microsoft Azure. This might be your "online for free" option. It is supposed to be "free for a month" (I haven't tried it). I assume that a subscription fee must be paid beyond that time.

The tutorials are here: http://hortonworks.com/tutorials/ and I suggest you start with the tutorials under the heading "Hello World".
