As of Storm 1.0 and above, some functionality (such as the worker-artifacts directory) require the use of symlinks. On Windows platforms, this requires that Storm either be run as an administrator or that certain group policy settings are changed.
In locked-down environments, both of these solutions are not suitable.
Where possible, an alternative option should be provided to the use of symlinks. For example, it may be possible to create additional copies of the worker artifacts directory for each worker (possibly inefficient) or provide the workers with the canonical path to the real directory.
