Subject Problem running SimpleShortestPathsComputation on CDH5 with Hadoop 2.2.0
Date Wed, 19 Feb 2014 21:12:56 GMT
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

        at org.apache.giraph.yarn.GiraphApplicationMaster.main(GiraphApplicationMaster.java:433)

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
-vip /user/stbesk/input/tiny-graph.txt
-vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat
-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.
Stefan
