Description

I got a NullPointerException when using sstableloader on 1.0.6. The cluster is using PropertyFileSnitch. The same configuration file is used for sstableloader.

The problem is if StorageService is initialized before DatabaseDescriptor, PropertyFileSnitch will try to access StorageService.instance before it finishes initialization.

 ERROR 01:14:05,601 Fatal configuration error
