I installed Hadoop-2.2 in a cluster of 4 nodes, following Hadoop YARN Installation: The definitive guide<http://www.alexjf.net/blog/distributed-systems/hadoop-yarn-installation-definitive-guide> .
The configurations are as follows: ~/.bashrc <http://pastebin.com/zQgwuQv2> core-site.xml<http://pastebin.com/rBAaqZps> hdfs-site.xml <http://pastebin.com/bxazvp2G> mapred-site.xml <http://pastebin.com/N00SsMbz> slaves <http://pastebin.com/8VjsZ1uu> yarn-site.xml <http://pastebin.com/XwLQZTQb> I started NameNode, DataNodes, ResourceManager and NodeManagers successfully, but no job can run successfully. For example, I run the following job: [root@Single-Hadoop ~]# yarn jar /var/soft/apache/hadoop-2.2.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar pi 2 4 The output is as follows: 14/05/10 23:56:25 INFO mapreduce.Job: Task Id : attempt_1399733823963_0004_m_000000_0, Status : FAILED Exception from container-launch: org.apache.hadoop.util.Shell$ExitCodeException: at org.apache.hadoop.util.Shell.runCommand(Shell.java:464) at org.apache.hadoop.util.Shell.run(Shell.java:379) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:589) at org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.launchContainer(DefaultContainerExecutor.java:195) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:283) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:79) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:662) 14/05/10 23:56:25 INFO mapreduce.Job: Task Id : attempt_1399733823963_0004_m_000001_0, Status : FAILED Exception from container-launch: org.apache.hadoop.util.Shell$ExitCodeException: at org.apache.hadoop.util.Shell.runCommand(Shell.java:464) at org.apache.hadoop.util.Shell.run(Shell.java:379) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:589) at org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.launchContainer(DefaultContainerExecutor.java:195) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:283) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:79) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:662) ... ... 14/05/10 23:56:36 INFO mapreduce.Job: map 100% reduce 100% 14/05/10 23:56:37 INFO mapreduce.Job: Job job_1399733823963_0004 failed with state FAILED due to: Task failed task_1399733823963_0004_m_000000 Job failed as tasks failed. failedMaps:1 failedReduces:0 14/05/10 23:56:37 INFO mapreduce.Job: Counters: 10 Job Counters Failed map tasks=7 Killed map tasks=1 Launched map tasks=8 Other local map tasks=6 Data-local map tasks=2 Total time spent by all maps in occupied slots (ms)=21602 Total time spent by all reduces in occupied slots (ms)=0 Map-Reduce Framework CPU time spent (ms)=0 Physical memory (bytes) snapshot=0 Virtual memory (bytes) snapshot=0 Job Finished in 24.515 seconds java.io.FileNotFoundException: File does not exist: hdfs:// Single-Hadoop.zd.com/user/root/QuasiMonteCarlo_1399737371038_1022927375/out/reduce-out at org.apache.hadoop.hdfs.DistributedFileSystem$17.doCall(DistributedFileSystem.java:1110) at org.apache.hadoop.hdfs.DistributedFileSystem$17.doCall(DistributedFileSystem.java:1102) at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) at org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:1102) at org.apache.hadoop.io.SequenceFile$Reader.<init>(SequenceFile.java:1749) at org.apache.hadoop.io.SequenceFile$Reader.<init>(SequenceFile.java:1773) at org.apache.hadoop.examples.QuasiMonteCarlo.estimatePi(QuasiMonteCarlo.java:314) at org.apache.hadoop.examples.QuasiMonteCarlo.run(QuasiMonteCarlo.java:354) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.examples.QuasiMonteCarlo.main(QuasiMonteCarlo.java:363) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:72) at org.apache.hadoop.util.ProgramDriver.run(ProgramDriver.java:144) at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:74) 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:212) Why would any job fail? Is it because the configurations are not correct?
