> 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...
