Description

There seem to be a lot of arcane errors being caused by the checkstyle rules/script. Real issues tend to be buried in this noise. Some examples :

1. "Line is longer than 80 characters" - this shows up even for cases like import statements, package names
2. "Missing a Javadoc comment." - for every private member including cases like "Configuration conf".

Having rules like these will result in a large number of pre-commit job failures. We should fine tune the rules used for checkstyle.
