Subject [jira] Commented: (HADOOP-4808) Blacklisting of TaskTrackers should take into account the user-ID
Date Tue, 09 Dec 2008 17:00:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12654846#action_12654846

Devaraj Das commented on HADOOP-4808:

Possibly true but we are trying to attack a lot of security issues with the security work
that we are doing. Also, things like HADOOP-4053 and HADOOP-4490 are positive steps in this
direction. I guess we should close all such loopholes going forward and this is one such issue...

> With HADOOP-4305, it is possible to blacklist TaskTrackers across jobs. It might make
sense to also take into account the users whose tasks are being run on the TaskTrackers, and
use it in the blacklisting strategy.
