Dear Hadoop users:
I followed the instructions of “Build and Install Hadoop 2.x or newer on Windows” and was able to build and install Hadoop 2.7.2 on a PC running Windowns10. Then, I tried to run a wordcount job on a single node environment, but this mapreduce job failed. Could someone please give me any feedback about my case? Do you have any ideas of why I am failing? If you need more information, I would be glad to send you! Thank you for your help in advance! --Juri Here is some relevant information: Yarn nodemanager shows: 16/03/08 15:24:25 INFO localizer.ResourceLocalizationService: Localizer failed java.lang.NullPointerException Yarn resaucemanager shows: 16/03/08 15:24:27 WARN resourcemanager.RMAuditLogger: USER=Van OPERATION=Application Finished - Failed TARGET=RMAppManager RESULT=FAILURE DESCRIPTION=App failed with state: FAILED PERMISSIONS=Application application_1457472180766_0001 failed 2 times due to AM Container for appattempt_1457472180766_0001_000002 exited with exitCode: -1000 For more detailed output, check application tracking page:http://Juri:8088/cluster/app/application_1457472180766_0001 Then, click on links to logs of each attempt. 16/03/08 15:24:27 INFO resourcemanager.RMAppManager$ApplicationSummary: appId=application_1457472180766_0001,name=word count,user=Van,queue=default,state=FAILED,trackingUrl=http://Juri:8088/cluster/app/application_1457472180766_0001,appMasterHost=N/A,startTime=1457472264161,finishTime=1457472267648,finalStatus=FAILED,memorySeconds=3991,vcoreSeconds=1,preemptedAMContainers=0,preemptedNonAMContainers=0,preemptedResources=<memory:0\, vCores:0>,applicationType=MAPREDUCE 16/03/08 15:24:29 INFO ipc.Server: Socket Reader #1 for port 8032: readAndProcess from client 192.168.1.72 threw exception [java.io.IOException: An existing connection was forcibly closed by the remote host] java.io.IOException: An existing connection was forcibly closed by the remote host Hadoop namenode shows: 16/03/08 15:24:29 INFO ipc.Server: Socket Reader #1 for port 9000: readAndProcess from client 127.0.0.1 threw exception [java.io.IOException: An existing connection was forcibly closed by the remote host] java.io.IOException: An existing connection was forcibly closed by the remote host The log message shows: Failed redirect for container_1457472180766_0001_02_000001 Failed while trying to construct the redirect url to the log server.
