I am running the example from http://giraph.apache.org/quick_start.html#qs_section_2 After successfully installing Giraph i create file /tmp/tiny_graph.txt and run
$HADOOP_HOME/bin/hadoop jar /usr/local/giraph/giraph-examples/target/giraph-examples-1.2.0-SNAPSHOT-for-hadoop-1.2.1-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/hduser/input/tiny_graph.txt -vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /user/hduser/output/shortestpaths -w 1 -ca giraph.SplitMasterWorker=false
I get an error
