Hello everybody,

it's been= a while since I last ran the PageRank example. Back then, there was no Gir= aphRunner, and the example cound be executed directly. Now, I am trying to = test something but I cannot manage to make the example work. I use the foll= owing command:

hadoop jar giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependenc= ies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimplePag= eRankVertex
-if org.apache.giraph.io.JsonLongDoubleFloatDoubleVertexInp= utFormat -w 1 -ip JSON_input -of org.apache.giraph.io.JsonLongDoubleFloatDo= ubleVertexOutputFormat -op outputJSON

The map phase proceeds up to 50% and then it freezes.
If I use 2 workers it freezes at 66%, with 3 workers at 75% etc.
