> Improve JobConf to add constructor to avoid sharing Credentials between jobs.
> By default the Credentials will be shared to keep the backward compatibility.
> We can add a new constructor with a new parameter to decide whether to share Credentials.
Some issues reported in cascading is due to corrupted credentials

> If we add this support in JobConf, it will benefit all job clients.
