[jira] [Created] (HADOOP-8450) tidy up src/test/system/c++/runAs

Colin Patrick McCabe created HADOOP-8450:
--------------------------------------------

             Summary: tidy up src/test/system/c++/runAs
                 Key: HADOOP-8450
                 URL: https://issues.apache.org/jira/browse/HADOOP-8450
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.0.0-alpha
            Reporter: Colin Patrick McCabe
            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...
