Subject [jira] Commented: (MAPREDUCE-1307) Introduce the concept of Job Permissions
Date Sun, 07 Feb 2010 09:50:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12830688#action_12830688

Devaraj Das commented on MAPREDUCE-1307:

The advantage with the file-system model is that it is really simple and would handle almost
all cases that we might come across. The ACL model is also fine though it is tedious to specify
that and pass it to the JobTracker. But it is good to look at the long term... So in that
sense, I am tending to agree with Hemanth/Vinod.
W.r.t condor, torque, i don't think that they have job level read/write permissions model.
They are more concerned with the queue operations. But it is something that could be checked.

> 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.
