Re: What is Overseer?

So, is Overseer really only an "implementation detail" or something that 
Solr Ops guys need to be very aware of?

I should have suggested three levels in my question: 1) important to average 
users, 2) expert-only, and 3) internal implementation detail. Yes, 
expert-only does have a place, but it is good to mark features as such.

Most people don't ever need to worry about the overseer - it's magic and
it will take care of itself.

The recent work on adding support for an "overseer role" in 4.7 was
specifically for people who *want* to worry about it.

I've updated several places in the solr ref guide to remove some
missleading claims about hte overseer (some old docs equated it to running
embedded zookeeper) and add some more info to the glossary..
