> Credentials (secret keys) can be passed to a job via mapreduce.job.credentials.json or mapreduce.job.credentials.binary .
> These credentials get submitted during job submission and are made available to the task processes.
> In HADOOP 1, these credentials get submitted and routed to task processes even if security was off.
> In HADOOP 2 , these credentials are transmitted only when the security is turned on.
> This should be changed for two reasons:
> 1) It is not backward compatible.

> 2) Credentials should be passed even if security is turned off .
