Hi, I am exploring Giraph 0.1 and was able to download, build, and run all the tests - all 58 passed.
I can also run the SimpleShortestPathsVertex test using the supplied giraph jar. However, when I copy the java src file into eclipse and build my own jar I get the following error which leads me to believe that something is going wrong with the ZK setup. 12/06/19 17:31:31 INFO mapred.JobClient: Running job: job_201206191708_0003 12/06/19 17:31:32 INFO mapred.JobClient: map 0% reduce 0% 12/06/19 17:32:14 INFO mapred.JobClient: Task Id : attempt_201206191708_0003_m_000000_0, Status : FAILED java.lang.IllegalStateException: run: Caught an unrecoverable exception onlineZooKeeperServers: Failed to connect in 10 tries! at org.apache.giraph.graph.GraphMapper.run(GraphMapper.java:641) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:764) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:370) at org.apache.hadoop.mapred.Child$4.run(Child.java:255) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:416) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1059) at org.apache.hadoop.mapred.Child.main(Child.java:249) Caused by: java.lang.IllegalStateException: onlineZooKeeperServers: Failed to connect in 10 tries! at org.apache.giraph.zk.ZooKeeperManager.onlineZooKeeperServers(ZooKeeperManager.java:658) at org.apache.giraph.graph.GraphMapper.setup(GraphMapper.java:409) at org.apache.giraph.graph.GraphMapper.run(GraphMapper.java:630) ... 7 more attempt_201206191708_0003_m_000000_0: log4j:WARN No appenders could be found for logger (org.apache.giraph.zk.ZooKeeperManager). attempt_201206191708_0003_m_000000_0: log4j:WARN Please initialize the log4j system properly. BTW, I needed to add the following line to get this to run from my own jar file... job.setJarByClass(SimpleShortestPathsVertex.class) Not sure if that is related but it seems that it will not run without this (it can not find SimpleShortestPathsVertex.
