> I recently updated a secure test cluster to trunk which includes the SPNEGO 
> patches for image transfer, without updating my configuration. Predictably, 
> the HTTP server won't initialize because I don't have the right principal set 
> up for the server. But, the NameNode started anyway, and just rejects all 
> image transfer requests with a 503. Instead, it should abort at startup if 
> the SPNEGO filter fails to init.
