Maja Kabiljo commented on GIRAPH-121:
-------------------------------------
You are having a problem because of
{noformat}ReflectionUtils.<VertexResolver>getTypeArguments(VertexResolver.class,
vertexResolverClass);{noformat}
from GraphMapper. This method doesn't work if the first argument is interface.
If you make VertexResolver to be an abstract class tests pass.
Also, I think that in BspUtils you should call
{noformat}conf.getClass(GiraphJob.VERTEX_RESOLVER_CLASS,
BasicVertexResolver.class, VertexResolver.class);{noformat}
> BasicVertexResolver should be implementation and VertexResolver should be
> interface
