Hi [~hitesh], I do not want to make you upset.
But the *-default.xml has some benefits:

1) We can directly get the default value of parameters by only creating an 
instance of TezConfiguration.

2) As a good project, we should have good customer documents. We are not 
expecting Tez users to know all Tez parameters by reading source code, right?

> TezConfiguration should have tez-default.xml like other Hadoop projects

> Like other Hadoop projects: MapReduce, Yarn, HDFS, etc. They all have two 
> configuration files. One is *-default.xml which contains default values, the 
> other is *-site.xml which allows user to customize configurations.
