Subject Re: ShortestPath Code execution on Hadoop 2.4.0 Inbox x
Date Tue, 12 Aug 2014 04:54:37 GMT
Hi,

You built Giraph for the Hadoop version 1.2.1 which is evident from your
command line
*hadoop jar
/usr/local/giraph/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-1.2.1-jar-with-dependencies.jar
*

You have the build Giraph against the Hadoop version you'll be using. If
you are using Hadoop 2.4.0, the command to build would be
*mvn -Phadoop_2 -Dhadoop.version=2.4.0 -DskipTests ...*
or
*mvn -Phadoop_yarn -Dhadoop.version=2.4.0 -DskipTests ...*

You can find this in the *README* file from Giraph trunk

Hope this helps.
