Subject [jira] [Created] (MAPREDUCE-4554) Job Credentials are not transmitted if security is turned off
Date Mon, 13 Aug 2012 17:00:38 GMT
Benoy Antony created MAPREDUCE-4554:

             Summary: Job Credentials are not transmitted if security is turned off
                 Key: MAPREDUCE-4554
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4554
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission, security
            Reporter: Benoy Antony
            Assignee: Benoy Antony

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 .
