这是一个 Docker 构建过程的输出，其中包括加载 .dockerignore 文件、加载 Dockerfile、从 Docker Hub 上下载 centos 镜像、安装 vim 软件包等步骤。但是在安装 vim 时出现了错误，可能是由于网络连接问题或者 yum 源配置问题导致的。

这个错误信息表明 Docker 在构建镜像时无法找到 Dockerfile 文件。请确认您在运行 `docker build` 命令时，当前工作目录下是否有 Dockerfile 文件，并且文件名是否正确。如果 Dockerfile 文件存在但是仍然出现这个错误，您可以尝试使用绝对路径指定 Dockerfile 文件的路径。例如，如果 Dockerfile 文件在 `/home/user/project` 目录下，您可以使用以下命令构建镜像：

docker build -t centos-hadoop /home/user/project

另外，也可能是 Docker 守护进程没有足够的权限来访问 Dockerfile 文件。请确认您是否以足够的权限运行 Docker。

<property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property>

This property is used to specify the auxiliary services to be run by the NodeManager. In this case, the value "mapreduce_shuffle" indicates that the NodeManager will run the MapReduce shuffle service. The MapReduce shuffle service is responsible for transferring data between the map and reduce tasks in a MapReduce job.
