Big data and hadoop exception when running a Map reduced programme

2015-05-27T20:25:47

I got the WordCount.java code from the internet and I tried to run it in eclipse after including the necessary libraries. But the code throws this exception:

2015-05-27 17:48:24,759 WARN  util.NativeCodeLoader     
(NativeCodeLoader.java:<clinit>(62)) - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Exception in thread "main" java.io.IOException: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.

Can you tell me what does this mean and how can i resolve it? I am very much new to Big data, Hadoop and map reduced programmes so please explain in detail. Thanks!
