Check the node where the problem was detected, and use the root user to check the java command on that machine.
I found that only deploying TiSpark checks for java.

Read the environment variables in the corresponding environment.

If TiSpark is not deployed, it can be ignored. If you want to deploy it, you need to set the environment variables with the user you deployed, not necessarily root.

I found the problem. There will be issues if the JDK used to install the TiSpark server is from Oracle. I changed it to OpenJDK and the problem was resolved.
