Hyunsik Choi commented on GIRAPH-64:

In my case, 'mvn package' is ok, but 'mvn assembly:assembly' incurs the error 
as I mentioned above.

> Currently, if a user wants to implement a Giraph algorithm by extending 
> {{Vertex}} they must also write all the boilerplate around the {{Tool}} 
> interface and bundle it with the Giraph jar (or get Giraph on the classpath 
> and playing nice with the implementation).  For example, what is included in 
> the PageRankBenchmark and what Kohei has done: 
> https://github.com/smly/java-Giraph-LabelPropagation  It would be better if 
> we had perhaps a Vertex implementation to be subclassed that already had all 
> the standard Tooling included such that all one had to run would be (assuming 
> the Giraph jar was already on the classpath):
> {noformat}hadoop jar my-awesome-vertex.jar my.awesome.vertex -i jazz_input -o 
> jazz_output -if org.apache.giraph.lib.in.text.adjacency-list.LongDoubleDouble 
> -of org.apache.giraph.lib.out.text.adjacency-list.LongDoubleDouble{noformat} 
> This wouldn't work with every algorithm, but would be useful in a large 
> number of cases.
