Is it a must to have /etc/hosts mapping or a DNS in a multinode setup?
Hi all,
Is it a must to have a /etc/hosts mapping or a DNS in a multinode storm
cluster? Can't supervisors talk to each other through ZooKeeper or nimbus
using IP addresses directly ?

Thank you very much Derek and Michael for you responses.
@Michael : Is there any specific reason for using hostnames / ips instead
of /etc/hosts mappings?

We don't use /etc/hosts mapping, we only use hostnames / ips.

I have not tried it, but there is a config for this purpose:
