Answer 1

You have to add this method

job.setJarByClass(WordCount.class);

before invoking the method

job.waitForCompletion(true);

As like following:

job.setJarByClass(WordCount.class);

job.waitForCompletion(true);

Answer 2

job.setJarByClass(WordCount.class); job.waitForCompletion(true);

Answer 3

I got this to work using JobConf#setJar(String)
