Besides class not found error, ...
Basically, your miniBSPCluster doesn't work with eclipse JUnit test and maven
build as below:

> Refactor BSPMaster and GroomServer to allow rpc methods reuse

>
> Key: HAMA-376
> URL: https://issues.apache.org/jira/browse/HAMA-376
> Project: Hama
> Issue Type: Improvement
> Components: bsp
> Affects Versions: 0.3.0
> Environment: Debian squeeze/sid, java 1.6.0_22, Hama revision 1090950
> Reporter: ChiaHung Lin
> Assignee: ChiaHung Lin
> Labels: patch
> Fix For: 0.3.0
>
> Attachments: HAMA-376.patch, HAMA-376.patch
>
>
> The current Hama BSPMaster and GroomServer make use of dispatch() and
> report() function for communication. But the directives passed in is
> composite, which is a bit difficult to customize new directives for future
> use. The refactored version allows to pass customized directives by extending
> Directive class; and the customized directive will be processed with
> corresponded handler. Also, directives are put into queue, so the rpc method
> e.g. dispatch() do not need to go through the whole method until the
> execution is finished.
