Alejandro Abdelnur updated MAPREDUCE-2457: ------------------------------------------ Attachment: MAPREDUCE-2457.patch > 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.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. -- This message is automatically generated by JIRA.
