Running a Processing Job on HDInsight
When you set up your sandbox using the Amazon EMR service, your
environmentcenteredonaspecificprocessingjob.Theprovisionofacluster

approach from that shown in the preceding demonstration, focusing first on
standing up your Hadoop cluster, meaning that to this point, you have not
actually processed any data.
To make sure that you understand the differences between the two service

sandbox by completing the following steps:
1. Download the
wordcount.js
file from the Chapter 13 materials
accompanying this topic. You also need the
wordcount.txt
file used
in the previous demo.
