Re: Problem running single source shortest path example in cluster

Hey Jyoti,
regarding the -of option, change it to -vof which corresponds to "vertex output format".

Hi..

I tried to run shortest path algo in cluster.. I follow giraph quick 
start documentation  to execute the algo..




 One thing I need to mention, on my cluster hadoop version is 1.2.1 
and giraph version is 1.1.0.. but when I build the giraph  the jar 
file which is create is named as



$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-_*hadoop-0.20.203.0*_-jar-with-dependencies.jar 




 Is it possible that in jar file name,  hadoop version is different 
from the version which is installed on my machine.??



  I typed following command





$HADOOP_HOME/bin/hadoop jar 
$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar 
org.apache.giraph.GiraphRunner 
org.apache.giraph.examples.SimpleShortestPathsComputation -vif 
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip 
/user/hduser/graph_input/graph.txt  -of 
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op 
/user/hduser/graph_output/shortestpaths -w 1




 I got tException in thread "main" 
org.apache.commons.cli.UnrecognizedOptionException: Unrecognized
