Hi I still trying to run the giraph shortest path example. So far I resolved most of the WARN from the hadoop userlogs files
But I still got this problem shown on the terminal: 13/01/19 16:34:48 INFO mapred.JobClient: Running job: job_201301191140_0006 13/01/19 16:34:49 INFO mapred.JobClient: map 0% reduce 0% 13/01/19 16:35:07 INFO mapred.JobClient: map 25% reduce 0% 13/01/19 16:35:10 INFO mapred.JobClient: map 50% reduce 0% 13/01/19 16:35:16 INFO mapred.JobClient: map 75% reduce 0% 13/01/19 16:35:18 INFO mapred.JobClient: Task Id : attempt_201301191140_0006_m_000000_0, Status : FAILED java.lang.Throwable: Child Error at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271) Caused by: java.io.IOException: Task process exit with nonzero status of 1. at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258) 13/01/19 16:35:28 INFO mapred.JobClient: map 100% reduce 0% 13/01/19 16:35:55 INFO mapred.JobClient: map 75% reduce 0% 13/01/19 16:36:00 INFO mapred.JobClient: Task Id : attempt_201301191140_0006_m_000000_1, Status : FAILED java.lang.Throwable: Child Error at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271) Caused by: java.io.IOException: Task process exit with nonzero status of 1. at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258) And in the logs file I funded this FATAL... 2013-01-19 16:34:58,851 INFO org.apache.giraph.comm.netty.NettyServer: start: Started server communication server: beb-1.bgu.ac.il/127.0.1.1:30000with up to 16 threads on bind attempt 0 with sendBufferSize = 32768 receiveBufferSize = 524288 backlog = 3 2013-01-19 16:34:58,852 INFO org.apache.giraph.graph.BspServiceMaster: becomeMaster: I am now the master! 2013-01-19 16:34:58,861 INFO org.apache.giraph.graph.BspService: process: applicationAttemptChanged signaled 2013-01-19 16:34:58,867 WARN org.apache.giraph.graph.BspService: process: Unknown and unprocessed event (path=/_hadoopBsp/job_201301191140_0006/_applicationAttemptsDir/0/_superstepDir, type=NodeChildrenChanged, state=SyncConnected) 2013-01-19 16:35:07,548 FATAL org.apache.giraph.graph.GraphMapper: uncaughtException: OverrideExceptionHandler on thread org.apache.giraph.graph.MasterThread, msg = generateVertexInputSplits: Got IOException, exiting... java.lang.IllegalStateException: generateVertexInputSplits: Got IOException at org.apache.giraph.graph.BspServiceMaster.generateInputSplits(BspServiceMaster.java:259) at org.apache.giraph.graph.BspServiceMaster.createInputSplits(BspServiceMaster.java:557) at org.apache.giraph.graph.BspServiceMaster.createVertexInputSplits(BspServiceMaster.java:622) at org.apache.giraph.graph.MasterThread.run(MasterThread.java:102) Caused by: java.io.IOException: No input paths specified in job at org.apache.giraph.io.GiraphFileInputFormat.listStatus(GiraphFileInputFormat.java:191) at org.apache.giraph.io.GiraphFileInputFormat.listVertexStatus(GiraphFileInputFormat.java:251) at org.apache.giraph.io.GiraphFileInputFormat.getVertexSplits(GiraphFileInputFormat.java:322) at org.apache.giraph.io.TextVertexInputFormat.getSplits(TextVertexInputFormat.java:61) at org.apache.giraph.graph.BspServiceMaster.generateInputSplits(BspServiceMaster.java:257) ... 3 more 2013-01-19 16:35:07,550 INFO org.apache.giraph.zk.ZooKeeperManager: run: Shutdown hook started. 2013-01-19 16:35:07,550 WARN org.apache.giraph.zk.ZooKeeperManager: onlineZooKeeperServers: Forced a shutdown hook kill of the ZooKeeper process. 2013-01-19 16:35:07,550 INFO org.apache.giraph.zk.ZooKeeperManager: onlineZooKeeperServers: ZooKeeper process exited with 1 (note that 143 typically means killed). I hope you can help my to solve this problem. till now I tried to run this on a pseudo distributed cluster and also on my real working Hadoop cluster, and got the same error. Thanks for the help Gil
