> The choice between a cluster and a single server is often made by testing the presence of
> "pdsh" or "pdcp", utilities which are not part of Trafodion.  Use of Trafodion should not
> prevent use of these software tools.
> This is an unnecessary extra complication for new users experimenting with Trafodion, since
> they may first install it on a single server, and probably build and test on a single server.
> Testing for pdsh is sometimes for a specific location, /usr/bin/pdsh, and sometimes for
> pdsh within the user's PATH, $(which pdsh).  The latter prevents moving pdsh to somewhere
> other than /usr/bin/pdsh.
> Some source files associated with this problem are:
