Getting "Array out of bound exception" Error while running mapreduce in cloudera VM

Question

I am trying to run my first word count on Cloudera VM. I am getting the

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at new_pack.word.main(word.java:52)

this error on line:

FileInputFormat.setInputPaths(conf, new Path(args[0]));

in the driver class.

I have copied the code mentioned in this Cloudera tutorial.

As noted at https://docs.cloudera.com/documentation/other/tutorial/CDH5/topics/ht_usage.html in step 5, you'll need to run the job with command-line arguments specifying where to find the input files and where to write the output:

$ hadoop jar wordcount.jar org.myorg.WordCount /user/cloudera/wordcount/input /user/cloudera/wordcount/output
