Subject [jira] [Updated] (MAPREDUCE-2505) Explain how to use ACLs in the fair scheduler
Date Fri, 20 May 2011 03:33:47 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2505?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matei Zaharia updated MAPREDUCE-2505:
-------------------------------------

    Attachment: MAPREDUCE-2505-branch-0.20-security.patch

Here's a patch for 0.20.203, but I'm a bit confused about where the work is being done for
the next release. Should I put this in the 0.20-security branch, or 0.20.203, or 0.20.204?

BTW I've decided to only commit this to the security branches because a) few people are likely
to use new releases of 0.20.x and 0.21 and b) the security branches actually have security
for the ACLs.

> The fair scheduler already works with the ACL system introduced through the mapred.queue.*
parameters, but the documentation doesn't explain how to use this. We should add a paragraph
or two about it.
