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 option: -of at org.apache.commons.cli.Parser.processOption(Parser.java:363) at org.apache.commons.cli.Parser.parse(Parser.java:199) at org.apache.commons.cli.Parser.parse(Parser.java:85) at org.apache.giraph.utils.ConfigurationUtils.parseArgs(ConfigurationUtils.java:189) at org.apache.giraph.GiraphRunner.run(GiraphRunner.java:74) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79) at org.apache.giraph.GiraphRunner.main(GiraphRunner.java:124) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:160) he following errror...
