Subject [jira] [Commented] (S4-60) Development mode for rapid application development and testing
Date Mon, 02 Jul 2012 10:32:21 GMT


Matthieu Morel commented on S4-60:

I uploaded a modification in branch S4-60 that allows to specify clusters configuration inline
when starting a Zookeeper instance. You would do something like:
{code}s4 zkServer -clusters={c=cluster1:flp=13000:nbTasks=1},{c=cluster2:flp=14000:nbTasks=10}
And there is also a test mode with by default 2 clusters named "testCluster1" and "testCluster2"
with 1 task each, that you may start like this:
{code}s4 zkServer -t{code}

Please let me know if you have other suggestions/improvements, otherwise I'll integrate that
into the main branch.

> During the development phase of S4 applications, we need to be able to avoid the "build-package-deploy"
cycle, which rapidly becomes cumbersome.
> Ideally, we'd be able to start S4 nodes and directly run the application from the classpath.
> This should be possible by providing a "DevelopmentDeploymentManager", that simply reads
an application classname as a parameter, and directly loads this class and therefore the application.
The only requirement is to have application classes and dependencies in the classpath.
