How to use OtherAction?
In looking at the ClusterActionHandlerSupport, I notice the before/after
OtherAction event. Is this functional? How can I trigger this event?

Yea, thats exactly what I'm looking for. Basically, I'd like to dynamically
create a shell script and execute it at any time, on any node in any cluster

I've opened https://issues.apache.org/jira/browse/WHIRR-324 for the
work on core that is needed to expose this.

I get that its not used. But is there some way I can "hook it up" so that I
can invoke it to execute shell scripts on running clusters?

The "other action" call was just to cover the case if new events were
added and not explicitly exposed in ClusterActionHandlerSupport. It's
not currently used.

By adding a new EXECUTE_ACTION, and extending
ClusterActionHandlerSupport to expose before/afterExecute methods?

I understand. Tom should be able to tell us more about the intended
usage scenario for OtherAction.
I just want to add that in 0.5.0 we've added support for remote script
execution to the CLI:
https://issues.apache.org/jira/browse/WHIRR-173
... and I believe what you need is a similar mechanism available in
the core API.

Re: How to use OtherAction?

Well, the reason I want to know is two fold. First, I'm using the whirr
core API to spin up and provision multiple clusters. But on one of my
clusters, I'd need to push out a shell script to execute after the configure
action happens. Basically, my code needs to generate a bunch of "stuff",
which it then uses to create the shell script dynamically, and I want to use
the OtherAction to push that shell script out to the instances in the
cluster to execute.
Second, I just like to know how generic extension points work, because I
like to come up with interesting ways to integrate APIs into what I'm
working on

What's you use case? Maybe there is another way.
As far as I know no service is using OtherAction event.
