RE: [druid-dev] any reason to still keep overlord as separate node?

I am one of those odd cases and agree with Gian on both accounts.

Hi Prashant,

The only issue that I can think of is that in some (super large) clusters, the 
coordinator and overlord can both be pretty demanding in terms of memory and it 
helps for scalability to have them be separate. But this is not the common case 
- most clusters are smaller or medium sized. So it makes sense for the default 
to be combining them. I would support a patch that changed the defaults and 
updated the docs accordingly.

Btw, since we are trying to migrate the dev mailing list to Apache, please 
cross post this sort of thing with dev@druid.apache.org, or even only post to 
that list.
