Aaron Levy commented on CASSANDRA-2356:
---------------------------------------
I would also really like to be able to control restarts on upgrades.
I get that auto-start is the "debian way", but it causes a fair amount of ops
pain. It also isn't clear if the debconf approach (CASSANDRA-2703) would give
any control over the service auto-starting on upgrade (which I would love to
have).
Exposing this through an /etc/default flag seems like a simple and commonly
used (albeit slightly sloppy) way of handling this.
If the flag defaults to "true", then both new/existing installs would have no
functional change, but we would at least have the option to easily control the
service restarts without resorting to other debian internals.

> Currently the debian package that installs cassandra starts cassandra by
> default. It sounds like that is a standard debian packaging convention.
> However, if you want to bootstrap a new node and want to configure it before
> it creates any sort of state information, it's a pain. I would think that
> the common use case would be to have it install all of the init scripts and
> such but *not* have it start up by default. That way an admin can configure
> cassandra with seed, token, host, etc. information and then start it. That
> makes it easier to programmatically do this as well - have chef/puppet
> install cassandra, do some configuration, then do the service start.
> With the current setup, it sounds like cassandra creates state on startup
> that has to be cleaned before a new configuration can take effect. So the
> process of installing turns into:
> * install debian package
> * shutdown cassandra
> * clean out state (data/log dirs)
> * configure cassandra
> * start cassandra
> That seems suboptimal for the default case, especially when trying to
> automate new nodes being bootstrapped.
> Another case might be when a downed node comes back up and starts by default
> and tries to claim a token that has already been claimed by another newly
> bootstrapped node. Rob is more familiar with that case so I'll let him
> explain it in the comments.
