> job submission should inject group.name (on the JT side)
> --------------------------------------------------------

> Key: MAPREDUCE-2457
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2457
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker
> Affects Versions: 0.21.0, 0.22.0
> Reporter: Alejandro Abdelnur
> Assignee: Alejandro Abdelnur
> Priority: Critical
> Fix For: 0.22.0
>
> Attachments: MAPREDUCE-2457-1.patch, MAPREDUCE-2457.patch
>
>
> Until Hadoop 0.20, the JobClient was injecting the property 'group.name' on
> the JobConf submitted to the JobTracker.
> Since Hadoop 0.21, due to security related changes, this is not done anymore.
> This breaks backwards compatibility for jobs/components that expect the
> 'group.name' to be automatically set at submission time.
> An example of a component being affected by this change is the FairScheduler
> where it is common to use the group.name as pool name. Different from other
> properties, a special characteristic of the group.name is that its value
> cannot be tampered by a user.
> For security reasons this should not be done (as it was done before) in the
> JobClient side. Instead, it should be done in the JobTracker when the JobConf
> is received.
