---------------------------------

             Summary: Quickstart Single node mode, cannot correctly finish the 
shortestpath task.
                 Key: GIRAPH-1186
                 URL: https://issues.apache.org/jira/browse/GIRAPH-1186

java 1.7

Giraph version: The latest one.

            Reporter: Yuhan Sun


I am following the guidance of the quickstart. But when I go to this step:

 

$HADOOP_HOME/bin/hadoop jar 
$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.2.0-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/input/tiny_graph.txt -vof 
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op 
/user/hduser/output/shortestpaths -w 1

 

I cannot successfully finish the task. The exception is like this:

 hduser@ubuntu:/usr/local/giraph/giraph-examples/target$ 
$HADOOP_HOME/bin/hadoop jar 
/usr/local/giraph/giraph-examples/target/giraph-examples-1.3.0-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

(default), do not allow any task retries (setting mapred.map.max.attempts = 1, 
old value = 4)

18/04/09 16:17:36 INFO job.GiraphJob: Waiting for resources... Job will start 
only when it gets all 2 mappers

 

As you can see, the .jar file name is little bit different from what is on the 
document. But I don't think it should be the problem.
