Description

Aurora uses the mesos replicated log.

If you don't run "mesos-log initialize" before starting aurora you'll get INFO messages in your aurora log:

I0814 15:18:38.346638 25141 replica.cpp:633] Replica in EMPTY status received a broadcasted recover request 
I0814 15:18:38.346796 25132 recover.cpp:220] Received a recover response from a replica in EMPTY status

It is has been deemed too dangerous to automatically run mesos-log initialize for the user (see AURORA-243).

It would be helpful if that error message was made more friendly and at the ERROR level. The message could explain what the user should do and the implications of doing so. Links to the docs would be helpful.

See http://wilderness.apache.org/channels/?f=aurora/2014-08-14#1408055261 for context
