Hello, I have deployed Giraph on the 8-node cluster (Giraph: release-1.0.0-RC2-152-g585511f, Hadoop:0.20.203.0rc1). As I do not have Internet on the cluster I have copied Giraph from my local computer where it worked well.
Now I am trying to test it on the cluster and have following issues: 1) When I running Giraph (with -h, just to test) it starts very slowly comparing to my local machine. 2) When I running a simple test it hangs like this: frolo@A11:~> $HADOOP_HOME/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.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/frolo/input/tiny_graph.txt -vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /user/frolo/output/shortestpaths -w 1 14/02/05 17:29:33 INFO utils.ConfigurationUtils: No edge input format specified.
