Yarn Nodemanager启动不了报YarnRuntimeException: Failed to initialize container executor error=13 权限不够

1、现象:有一个节点的NodeManager启动不了。

  后台报错日志如下:

2、container-executor的权限如图所示:

  3、问题排查过程

  yarn后台运行的用户是mr,但是其不在users组中,导致没有权限报错。

  解决方法:将mr加到users用户组中即可,为了减小影响使用root用户执行usermod -G users mr即可,此命令修改了mr用户的附属群组。

其他:

  有可能是其他权限问题导致,解决方案参见:
