Hi.

 

I checked out and built Giraph for Cloudera CDH5 with Hadoop 2.2.0 using the following:

git clone git://git.apache.org/giraph.git snapshot_from_git
cd snapshot_from_git
mvn -Phadoop_yarn -Dhadoop.version=2.2.0 clean package –DskipTests

 

When I run the sample application org.apache.giraph.examples.SimpleShortestPathsComputation I get the following exception:

 

LogType: gam-stdout.log

Here is the command I used to run the application:

hadoop jar giraph-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsComputation

-vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat

–op /user/stbesk/output/shortestpaths

-w 2

-ca giraph.SplitMasterWorker=true

-ca giraph.zkList=localhost:2181

-yj giraph-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar,giraph-examples-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar

 

What am I doing wrong? Appreciate any suggestions for what to try next.

 

Thanks.
