SimpleShortestPathsVertex: Output Format Code Not Recognised.

[Ghufran Malik <gh...@gmail.com>]

Hello I am a beginner with Apache Giraph and am using Apache Giraph 1.0.0
with Hadoop 0.20.203.0. I am having trouble running the
SimpleShortestPathsVertex example. When running the following command:

 

hadoop jar
/home/ghufran/Downloads/giraph-folder/giraph-1.0.0/giraph-examples/target/gi
raph-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/ghufran/input/input-json -of
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/ghufran/output1 -w 1

 

The map job fails giving me the following output:

 

14/02/13 20:16:13 INFO utils.ConfigurationUtils: No edge input format
specified. Ensure your InputFormat does not require one.
14/02/13 20:16:13 WARN job.GiraphConfigurationValidator: Output format

>From what I understand the output format code "-of
org.apache.giraph.io.formats.IdWithValueTextOutputFormat " is not
understood. I tried to run the command again with -vof instead of -of but I
than got an error saying that the -vof option was not recognised:

Any help with this would be greatly appreciated.

 

 

Thanks in advance
