Naganarasimha G R commented on YARN-4452: ----------------------------------------- Thanks for reviewing and committing the patch [~djp], and [~wlin] for raising the issue. bq. patch will be commit to 2.6 (for 2.6.4) instead of 2.6.3 given 2.6.3 RC is out and pass the vote. As i had already branch for 2.6.3 in my machine, created the patch for the issue on top of it (also its same as 2.6 branch). > NPE when submit Unmanaged application > ------------------------------------- > > Key: YARN-4452 > URL: https://issues.apache.org/jira/browse/YARN-4452 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.7.1, 2.6.2 > Reporter: Naganarasimha G R > Assignee: Naganarasimha G R > Priority: Critical > Fix For: 2.8.0, 2.7.3, 2.6.4 > > Attachments: YARN-4452-branch-2.6.3.v1.001.patch, > YARN-4452.v1.001.patch, YARN-4452.v1.002.patch > > > As reported in the forum by Wen Lin (w...@pivotal.io) > {quote} > [gpadmin@master simple-yarn-app]$ hadoop jar > ~/hadoop/singlecluster/hadoop/share/hadoop/yarn/hadoop-yarn-applications-unmanaged-am-launcher-2.6.0.3.0.0.0-120.jar > Client --classpath ./target/simple-yarn-app-1.1.0.jar -cmd "java > com.hortonworks.simpleyarnapp.ApplicationMaster /bin/date 2" > {quote} > error is coming as > {code} > org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Error in > handling event type REGISTERED for applicationAttempt > application_1450079798629_0001 > 664 java.lang.NullPointerException > 665 at > org.apache.hadoop.yarn.server.resourcemanager.metrics.SystemMetricsPublisher.appAttemptRegistered(SystemMetricsPublisher.java:143) > 666 at > org.apache.hadoop.yarn.server.resourcemanager.rmapp.attempt.RMAppAttemptImpl$AMRegisteredTransition.transition(RMAppAttemptImpl.java:1365) > 667 at > org.apache.hadoop.yarn.server.resourcemanager.rmapp.attempt.RMAppAttemptImpl$AMRegisteredTransition.transition(RMAppAttemptImpl.java:1341) > 668 at > org.apache.hadoop.yarn.state.StateMachineFactory$SingleInternalArc.doTransition(StateMachineFactory.java:362) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
