我在 hadoop-2.7.0 上运行了一个 MapReduce 作业,但 MapReduce 作业无法启动,并且遇到以下错误:
Job job_1491779488590_0002 failed with state FAILED due to: Application application_1491779488590_0002 failed 2 times due to AM Container for appattempt_1491779488590_0002_000002 exited with exitCode: 1

这个错误的原因是什么?我该如何解决这个问题?
任何帮助表示赞赏。
检查资源管理器上的日志:
you got this error:
现在打开终端并检查实际问题:
yarn logs -applicationId <APP_ID>
示例:APP_ID = application_1535002188113_0001
就我而言,它显示权限问题:
所以我给了它:
sudo -u hdfs hadoop fs -chmod 775 /user/history
or
sudo -u hdfs hadoop fs -chmod 777 /user/history
