Hi all, when stopping components of pinot (controller, broker, server) using admin script, sometimes component is not stopped and even is not logged.

apache-pinot-0.9.3-bin/bin/pinot-admin.sh StopProcess -controller/-server/-broker

How do I know why it's not shutting down when executing stop command ? Also, is there any other way to stop pinot component safely? Thank you in advance.

Do you see anything in the logs?

@Mayank when executing stop server command , it shows like this. but server is still running . and it is not logged in pinot server log file.

Is this for production or local testing? Typically, in production, you’d use docker/k8s and that should be a more graceful way to handle startup/shutdown.

we are not using docker/k8s. we are using cluster consisting of multiple servers. is there other stop command for cluster? (not quick start)

We had this issue when we had server nodes which had previously hit an OutOfMemoryError but did not shutdown as a result. When you try a graceful shutdown nothing happens. The pattern I end up using for these scenarios is this: netstat -tulpn | grep LISTEN | grep <pinotPort> and then kill -9 the pid from above Could probably combine this with xargs into 1 command.
