Hadoop Exception while unregistering exited with exitCode: 1 报错处理

问题现象：

查看 hadoop  resourcemanager.log 查看有如下异常：

Application application_1508235352644_0005 failed 2 times due to AM Container for appattempt_1508235352644_0005_000002 exited with exitCode: 1For more detailed output, check application tracking page:http://h1:8088/cluster/app/application_1508235352644_0005Then, click on links to logs of each attempt.Diagnostics: Exception from container-launch.Container id: container_e22_1508235352644_0005_02_000001Exit code: 1Stack trace: ExitCodeException exitCode=1:at org.apache.hadoop.util.Shell.runCommand(Shell.java:582)at org.apache.hadoop.util.Shell.run(Shell.java:479)at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:773)at org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.launchContainer(DefaultContainerExecutor.java:212)at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:302)at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:82)at java.util.concurrent.FutureTask.run(FutureTask.java:266)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)at java.lang.Thread.run(Thread.java:745)Container exited with a non-zero exit code 1Failing this attempt. Failing the application.

应用客户端，我这是自己配置的log4j2 生成日志，会在所在Active 节点生成 日志

日志中有如下异常：

解决办法：

参考apache 官网https://issues.apache.org/jira/browse/MAPREDUCE-5721 点击打开链接

可以看到 说是jobhistory 的配置，检查你 客户端程序 mapre-site.xml 配置：

查看： jobhistory的配置是否有问题，我检查了下我出现问题的原因是因为 没有h4这台机器，jobhisroty运行在h3
