Re: Should nimbus.seeds always be refreshed in storm.yaml?

[Jungtaek Lim]

Storm finds leader Nimbus via connecting to known Nimbus and query, so it's
safe unless all of Nimbus in nimbus.seeds are dead.

But, AFAIK, runtime update of Nimbus seeds (via discovery) doesn't happen.
(Anyone please correct me if I'm wrong.)
Might be better to have it for H/A (run discovery for given interval, or
whenever connection to Nimbus), but not sure we would also want to also
update the config file.

Thanks,

Which version of Storm are you using? If you are using 1.x then you can use
nimbus HA by configuring respective nimbus.hosts.

Should nimbus.seeds always be refreshed in storm.yaml?

Hi,

We are setting up a storm cluster where a nimbus node would be
automatically added to the nimbus cluster if any nimbus machine fails.

In such a scenario, the new nimbus node will have a different host-name/IP
address.

If that happens, is it absolutely mandatory for all the
workers/supervisors/remaining-nimbuses to have their storm.yaml files
updated immediately?
Or they can get to know about the new nimbus node from the existing nimbus
nodes?
(We will update the storm.yaml for any node that is restarting, but it is
somewhat difficult to trigger the updation of storm.yaml whenever a new
nimbus node joins the nimbus cluster).

Some help on the same would be appreciated.
Thanks,
SG
