You will notice that Eclipse will show lots of errors in WordCount.java file. Copy the file into the eclipse project under “src”.Ĥ. If output of your system matches with the given output then Congratulations!, you have successfully configured Hadoop on your machine else go through the steps again and double check whether any of the steps are missed.ġ.Start Eclipse and create a new Java programģ.Let’s see if everything is set up correctly.
