Subject [jira] [Commented] (S4-93) Local Mode for testing
Date Tue, 21 Aug 2012 14:21:38 GMT


Matthieu Morel commented on S4-93:

Right, whatever can facilitate development is usually worth having!

Currently, the easiest way to start nodes locally is to skip the deployment process and to
directly run the {{org.apache.s4.core.Main}} class, passing as parameters the cluster name
and the app class. E.g. {code}-c=C2 -appClass=org.apache.s4.example.twitter.TwitterCounterApp
{code} options for starting the Twitter app for instance (after making sure the classpath
includes platform + app classes). 

This is what the "s4 adapter" command does. It's also very easy to do that from an IDE. 

(and by the way, I should add that to the wiki!)

Are you suggesting another way, maybe better? Are you looking for a simple command to run
an app without the deployment step?

> Providing Local mode can be useful for app testing. In local mode, We can start a testing
zookeeper server and use threads to simulate nodes process.
