Claudio, this was the missing thing I was looking for. Now the simple random graph generator works well. Thanks again. Best wishes Mirko On Tue, Nov 5, 2013 at 8:55 PM, Claudio Martella wrote: > I don't see errors in your logs. The parameters that defines the total > number of vertices create

I don't see errors in your logs. The parameters that defines the total number of vertices created is giraph.pseudoRandomInputFormat. aggregateVertices. On Tue, Nov 5, 2013 at 1:05 PM, Mirko Kämpf wrote: > Hi, > > after I changed the code of the PseudoRandomVertex and > PseudoRandomEdgeInputF

Hi, after I changed the code of the PseudoRandomVertex and PseudoRandomEdgeInputFormat I can compile and run the job but it will stop after the 10 minute timeout. I think there is still some parameter missing or defined wrong. Claudio wrote, one has to set the number of vertexes, but how? T

It says no EdgeInputFormat is given. So you might have forgotten to give edge list? In the code it says: JsonLongDoubleFloatDoubleVertexInputFormat * VertexInputFormat that features long vertex ID's, * double vertex values and float * out-edge weights, and double message types, * specifi

Hi Suman.. In earlier posts,you detailed about how to execute our own giraph job in 4 steps.. I successsfully completed 3 steps. I gave the following command . bin/hadoop jar $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar org.ap
