Subject [jira] [Commented] (MAPREDUCE-2767) Remove Linux task-controller from 0.22 branch
Date Sat, 06 Aug 2011 23:17:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13080487#comment-13080487

Konstantin Shvachko commented on MAPREDUCE-2767:
------------------------------------------------

Aren't we trying to remove the entire palm because one nail grew ugly?
We can just turn it off by throwing, e.g. UnsupportedOperationException on an attempt to use
it. And then turn it back on when the fix is provided.

> There's a potential security hole in the task-controller as it stands. Based on the discussion
on general@, removing task-controller from the 0.22 branch will pave way for 0.22.0 release.
(This was done for the 0.21.0 release as well: see MAPREDUCE-2014.) We can roll a 0.22.1 release
with the task-controller when it is fixed.
