Sergey Edunov updated GIRAPH-1113:
----------------------------------
Description: Vertex combiners only have access to vertex values so if
something happens and exception is thrown there is no way to track it back to
particular vertex. We need to handle these exceptions higher in the code and
re-throw with extra information
> Errors from vertex combiner don't have vertex id, which makes it very hard to
> debug.
