当我运行mapreduce作业时，它只是挂起并最终失败（大约20分钟后）。
这是我在8088上看到的错误代码

exited with exitCode: -100 due to: Container expired since it was unused.Failing this attempt.. Failing the application.

对这个问题有什么想法吗？
我正在运行hadoop2.2。
更新：
问题似乎与此有关：

Container killed by the framework, either due to being released by the application or being 'lost' due to node failures etc. have a special exit code of -100.

更新2：
这些错误来自resourcemanger日志：
