             Summary: Compile error when compiling the giraph shortest path problem: getOutEdgeMap()
                 Key: GIRAPH-529
                 URL: https://issues.apache.org/jira/browse/GIRAPH-529
             Project: Giraph
          Issue Type: Bug
         Environment: Fedora 18(64-bit), hadoop-1.0.4 version, giraph-0.1.0 version
            Reporter: eunjihwang


I have some problem when I compiling the giraph shortest path problem

I can't understand exactly getOutEdgeMap() method.
Should I implement it? 

and also I have other compile errors.

I just write a source code like this; https://github.com/aching/Giraph/wiki/Shortest-Paths-Example

I attach error messages.
