Description

Proposed directory structure layout:

$prefix/$cluster-$role/stacks
                      /config
                      /logs/
                      /data/disk-*/
                      /pkgs/hadoop-*.tar.gz
                      /config/hadoop/core-site.xml

One optimization that Owen proposed is to make the directory structure shorter for client.

$prefix/$cwd/stacks
            /config
            /logs
            /data/disk-*/
            /pkgs/hadoop-*.tar.gz
            /config/hadoop/core-site.xml

Action send by controller will contain "current working directory", which agent will record the cluster and role mapping to current working directory.
