我现在发现没使用到这些组件，那么我可以卸载吗，该怎么卸载呢？
执行命令停止spark 也不起作用
ansible-playbook -i inventory.ini stop_spark.yml
另外 cd /data/deploy/spark/sbin
sh stop-all.sh 也停止不了spark
现在有什么影响吗？这些主机上有配置的信息吗？
有配置信息的， 现在没使用spark，想停止并卸载掉，并空出些内存new 9.txt (2.2 KB)

你好，停止 tispark-server 即可，走缩容流程即可，tiup cluster scale-in cluster-name -N ip:port
