Subject [jira] [Commented] (S4-60) Development mode for rapid application development and testing
Date Thu, 28 Jun 2012 16:19:42 GMT

    [ https://issues.apache.org/jira/browse/S4-60?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13403193#comment-13403193
] 

Matthieu Morel commented on S4-60:
----------------------------------

The current mode still requires a developer to:
* start a Zookeeper instance ({{s4 zkServer}})
* define a subcluster in Zookeeper

We could simplify the process by merging these operations with defaults in an s4 task such
as: {{s4 zkServer -testMode}}. It would automatically create 2  subclusters _testCluster1_
and _testCluster2_ with 1 node each, listening on predefined ports. (Defaults would be overridable.)

> 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.
