Run under supervision

[Huiliang Zhang <zh...@gmail.com>]

Hi,

What does "under supervision" mean when starting NIMBUS like in the
following?

Run the command "bin/storm nimbus" *under supervision* on the master
machine.

What should I do to make it under supervision?

Thanks

For a supervisord config example take a look at:
http://www.michael-noll.com/tutorials/running-multi-node-storm-cluster/#configure-supervisord-for-storm

Note, however, that the link above uses the outdated supervisord 2.x.  I
recommend to go use the newer supervisord 3.x.  I recently published
Puppet modules that automate running Storm with supervisord 3.x:
https://github.com/miguno/puppet-storm
https://github.com/miguno/puppet-supervisor

See
https://github.com/miguno/puppet-storm/blob/master/manifests/nimbus.pp
for the supervisord related setup.

(And in case you need to build an RPM for supervisord 3.x take look at
https://github.com/miguno/wirbelsturm-rpm-supervisord)

Hope that helps,
Michael

Generically, something that will babysit the process should it die (Storm
reliability relies on processes being restarted  when there is an error
since they will "fail fast").

Specifically, check out:
