["Gianmarco De Francisci Morales (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-3008?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gianmarco De Francisci Morales updated PIG-3008:
------------------------------------------------

    Attachment: checkstyle.xml

Agreed, let's start with this.
Here a first stab for a checkstyle with FileTabCharacter, Indentation, and RegexpSingleLine for trailing white space.
I threw in a few other things which I think are useful as well:
Checking all files have Apache header, checking imports and using ==/!+ with Strings.

> This JIRA exists mainly to get a conversation started. We've talked about it before, and it's a tricky issue. That said, some of the Pig code is super, super gnarly. We need some sort of path that will let it eventually be fix-able.
> I posit: any file that hasn't been touched for over 6 months is eligible for a whitespace patch.
