Hi,
I'm a new Giraph user. I installed Hadoop 1.2.1 with Giraph 1.0.0. I'd
testing a tiny graph obtained from this blog:
http://www.sbarjatiya.com/notes_wiki/index.php/Install_giraph_in_hadoop_node
which use the Shortest Path algorithm but when checking the output, the
file is empty.
The line command is :
../hadoop/bin/hadoop jar
/opt/hadoop/giraph/giraph-examples/target/giraph-examples-1.0.0-for-hadoop-0.20.203.0-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsVertex -vif
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
-vip /user/hduser/input/tiny_graph.txt -of
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hduser/output/shortestpaths2 -w 1
On the terminal I have this :
