Hi, Vikalp
I think you complied as wrong hadoop version.
Try below command
If you use yarn
mvn -Phadoop_yarn -Dhadoop.version=2.4.0 -DskipTests package
or if you use just hadoop2
mvn -Phadoop_2 -Dhadoop.version=2.4.0 -DskipTests package
Best Regards, Seong-il

Title : ShortestPath Code execution on Hadoop 2.4.0 Inbox x
Hi everyone,
I am new to Apache Giraph and would like execute Shortestpath and PageRank
example code on Hadoop 2.4.0 single node cluster (my machine) having Centos 6.5.
I have successfully build Giraph on my machine but unable to execute
ShortestPath code.
Please let me know if there are any dependencies to be resolved before code
execution.
P.S. :
Command used:
hadoop jar
/usr/local/giraph/giraph-examples/target/giraph-examples-1.1.0-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/hadoop/input/tiny_graph.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hduser/output/shortestpaths -w 1 -ca giraph.SplitMasterWorker=false
