Subject [jira] Commented: (MAPREDUCE-1307) Introduce the concept of Job Permissions
Date Tue, 16 Feb 2010 06:04:30 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12834092#action_12834092
] 

Devaraj Das commented on MAPREDUCE-1307:
----------------------------------------

Some comments summarizing an offline discussion with Vinod:
1) Protect getTaskDiagnostics() APIs also w.r.t access control.
2) ACLs for jobs should be displayed as part of jobdetails (the front page for jobs where
all high level info is displayed).
3) If a user gets an access control error, he should be informed about the configured ACLs
for the job.
4) Make the ACL part of the JobStatus object so that it is visible to all interested parties
who might be interested (including the command line to get the job status). Also, the CompletedJobStatusStore
can make use of this and enforce access control..
5) Can we have the default ACL for job view enabled for the groups the user belongs to? Current
patch makes the default to be '', meaning no one else except job-owner and superuser/supergroup
can see others' jobs if mapreduce.cluster.job-authorization-enabled is set to true.

> It would be good to define the notion of job permissions analogous to file permissions.
Then the JobTracker can restrict who can "read" (e.g. look at the job page) or "modify" (e.g.
kill) jobs.
