I'm using a VM and have a cluster consists of 1 master and node and 3 nodes else, I installed hadoop and copy it to all nodes and deploying giraph in master but I don't know that I should to copy giraph folder too to all nodes or not!!, and I'm using real dataset wikiTalk and my command line is
$HADOOP_HOME/bin/hadoop jar $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.3.0-SNAPSHOT-for-hadoop-2.5.1-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimplePageRankComputation -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/hduser/input/WikiTalk.txt -vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /user/hduser/output/wikiTalk11_output -w 4
but I found this exception
