William Jones created GIRAPH-974:
------------------------------------
Summary: Unable to run simple Giraph jobs
Key: GIRAPH-974
URL: https://issues.apache.org/jira/browse/GIRAPH-974
Project: Giraph
Issue Type: Bug
Components: build, documentation
Affects Versions: 1.0.0
Reporter: William Jones
I'm going through the Apache Giraph quick start tutorial:
http://giraph.apache.org/quick_start.html and have successfully setup a
pseudo-distributed hadoop cluster and have successfully run the example
mapreduce jobs.
However when moving to the Giraph section, I've installed Giraph using maven
and I'm for some reason unable to run the simplest of Giraph jobs.
I've added the tiny_graph to my hdfs, but running their example command:
hduser@fonz-VirtualBox:~/Giraph$ $HADOOP_HOME/bin/hadoop jar
/usr/local/giraph/giraph-examples/target/giraph-examples-1.2.0-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/hduser/input/tiny_graph.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hduser/output/shortestpaths -w 1
Gives me:

Any ideas as to why this has failed would be greatly appreciated!
Thanks very much.
