Sorry I don't see what you are referring to in hadoopFile? Do you mean
hadoopRDD, which already takes a Jobconf?
We need a JobConf for addCredentials routine to work. I could look at add
the credentials another way but the nice thing about creating another JobConf
is if the user passes in a JobConf instance creating a new one handles
transferring any credentials from that one as well.
