i have problem running given illustration simpleshortestpathscomputation tiny_graph.txt. stuck @ process of cut down part after map part. shows me 100% maps , 0% reduced , hangs there time. having hard time looking solutions in web. has come across problem? way, hadoop version 1.2.1 while giraph 1.1.0. give thanks you!

the problem giraph doesn't have reducer reducer never executes. moreover, process terminates when vertices vote halt, never happens.

here quick patch it. https://issues.apache.org/jira/browse/giraph-756
