> 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
> at
> https://github.com/Cascading/cascading/commit/45b33bb864172486ac43782a4d13329312d01c0e
> If we add this support in JobConf, it will benefit all job clients.
