Description

Credentials (secret keys) can be passed to a job via mapreduce.job.credentials.json or mapreduce.job.credentials.binary .

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.
