there. I have hadoop 2.4.1 running on ubuntu. Executing jps command, I am getting this output:
7394 DataNode3794 org.eclipse.equinox.launcher_1.5.0.v20180512-1130.jar8053 NodeManager7190 NameNode7638 SecondaryNameNode7868 ResourceManager8364 Jpsis it normal to get "3794 org.eclipse.equinox.launcher_1.5.0.v20180512-1130.jar" along with the output of jps?
I am asking because didn't get it before. Suddenly, it started to give this result with jps.

jps lists all Java processes on your machine. It is not specific to Hadoop.
If you had Eclipse, IntelliJ, Netbeans, whatever running on that machine, then you will see those processes
The full form of JPS is Java Virtual Machine Process Status.JPS command is used to check if a specific daemon is up or not. The command of JPS displays all the processes that are based on Java for a particular user. The command of JPS should run from the root to check all the operating nodes in the host.
