any reason to still keep overlord as separate node?

[Prashant Deva]

i feel atleast the documentation should be written to assume that overlord+coordinator is the default config and separate overlord is the 'legacy' one.

is there any actual issues holding keeping overlord as separate node?

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 d...@druid.apache.org, or even only post to that list.
