Subject [jira] [Commented] (HADOOP-8450) tidy up src/test/system/c++/runAs
Date Thu, 31 May 2012 20:56:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286929#comment-13286929

Todd Lipcon commented on HADOOP-8450:

AFAIK this was part of Herriot, which I don't think runs anymore with trunk. Given it lacks
an active maintainer and I'm not aware of anyone using it, I think we should remove src/test/system.

>             Project: Hadoop Common

>            Priority: Trivial
> runAs is a binary in the hadoop-common project.  It seems to allow you to run a hadoop
daemon as another user.  However, it requires setuid privileges in order to do this.
> * Do we still need this binary?  Who is using it and are there better solutions out there?
 My understanding is that setuid binaries are something we generally try to avoid.
> * If we do need it, can we add some documentation about it somewhere?
> * Should this binary be in the src/test directory?  It doesn't seem to be testing anything.
> Hopefully that covers everything...
