博客介绍了yarn-site.xml配置文件，指出yarn.nodemanager.resource.memory-mb的value不能小于1G，因电脑内存小，将其改为1024后，可通过start-yarn.sh命令正常启动yarn，还需用scp命令复制到nodemanager节点，最后提及正常启动后的节点详情。

出错原因，yarn.nodemanager.resource.memory-mb的value不能小于1G，即（1024）。自己电脑内存小，刚开始到每个虚拟机的内存小，改为1024后就能通过start-yarn.sh命令正常启动yarn（需要使用scp yarn-site.xml slave3:$PWD命令复制到nodemanager节点）。
