Hi ..
I want to run my own giraph program. I made some modification to already
existiing SimpleShortestPathsComputation program.
I compiled it and created a jar file.
I gave 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.apache.giraph.GiraphRunner -libjars /home/hduser/sp2.jar
SimpleShortestPathsComputation*1* -vif
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
-vip /user/hduser/sp_input/tiny_graph.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hduser/sp_output7/shortestpaths -w 1
I am getting following error..
Exception in thread "main" java.lang.ClassNotFoundException:
