When using multiple hudson nodes, the clearcase snapshot directory must be
unique on each node (you can only have one snapshot view with a given name in
clearcase). We currently configure this to be unique per node by using the
${HOSTNAME} variable in the clearcase view name.

Because the snapshot directory is unique per host, we will need to customize the
clover and junit directories to match as well. It would be great if they
supported the ${HOSTNAME} environment variable as well.

As it stands, the impact is that if we want JUnit and Clover reports to be
processed, we have to tie our job to a specific node.
