Description

Recently we wrote the wordcount example from scratch using Tez API's in TEZ-689. The code shows some room for improvement in making the Tez API's more concise and less error prone. This jira tracks some of those changes. The improvements in this jira will be reflected in the cleanliness and conciseness of the word count example job.
