停止服務:
sudo /etc/init.d/hadoop-yarn-resourcemanager stop
啟動服務:
sudo /etc/init.d/hadoop-yarn-resourcemanager start
檢視服務狀態:
sudo /etc/init.d/hadoop-yarn-resourcemanager status
ps:請勿使用restart命令
在EMR4.x,5.x中服務已新增到upstart服務了,查詢服務:
sudo initctl list
停止服務:
sudo stop hadoop-yarn-resourcemanager
啟動服務:
sudo start hadoop-yarn-resourcemanager
