Sergio Bossa commented on CASSANDRA-12039:
------------------------------------------
[~beobal],
I've pushed one more commit addressing your latest points, and I'll look into
writing any dtests. Also:
bq. One thing that we should note is that when pre-join tasks are executed as a
result of manually joining (i.e. start in write survey mode, then join via
nodetool/JMX), the value of the bootstrap flag is always false. Obviously, this
might not always be accurate as a node can perfectly well start up in survey
mode but also perform bootstrap before an operator joins it. Short of exposing
the overload of joinRing and extending the nodetool join command, I'm not sure
there's any practical solution to this.
I think we could actually leverage the bootstrap state, which is left pending
at {{IN_PROGRESS}} during write survey and then set at {{COMPLETED}} when
finally joining. But, I'm not really sure why the write survey mode works that
way, that is why the bootstrap state is left in progress, and I don't want to
rely on some unintentional behaviour: any ideas, [~brandon.williams]?

> Custom index implementations might need to be notified when the node finishes
> bootstrapping in order to execute some blocking tasks before the node itself
> goes into NORMAL state.
> This is a proposal to add such functionality, which should roughly require
> the following:
> 1) Add a {{getPostBootstrapTask}} callback to the {{Index}} interface.
> 2) Add an {{executePostBootstrapBlockingTasks}} method to
> {{SecondaryIndexManager}} calling into the previously mentioned callback.
> 3) Hook that into {{StorageService#joinTokenRing}}.
> Thoughts?
