Benoy Antony commented on MAPREDUCE-4554:
-----------------------------------------
The patch adds a test case for 1.1 and 2.0 .
It also removes security on/off checks when transmitting credentials.

> Key: MAPREDUCE-4554
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4554
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: job submission, security
> Affects Versions: 2.0.0-alpha
> Reporter: Benoy Antony
> Assignee: Benoy Antony
> Attachments: MR_4554_1_1.patch, MR_4554_trunk.patch

>
> 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 .
