Why jps is not showing any results on execution

Technical Discussions
#1

I am following some tutorials that ask me to run jps to check the processes
that are running in the application. But running this command on the terminal
is resulting into nothing in my case. Where am I going wrong?

As per the documentation:

The jps tool lists the instrumented HotSpot Java Virtual Machines (JVMs) on the target system. The tool is limited to reporting information on JVMs for which it has the access permissions.

Since most of the usual services like node managers or data nodes are running with a different user than yours, therefore, it does not show up.
