Hadoop on VMWare - Mapreduce example program fails to run

I am trying to run hadoop 3.2.0 on Ubuntu 18.10 running as a VM over Win10.
Want to execute a sample word count program to verify that the installation was successful and that hadoop has been properly configured.

When I try to run the included example jar by using command:

bharath@ubuntu:/usr/share/hadoop$ bin/hadoop jar
share/hadoop/mapreduce/hadoop-mapreduce-examples-3.2.0.jar grep input
output ‘dfs[a-z.]+’

I get this on the terminal:

I am new to hadoop and even Java so I am unable to make much sense of what any of this means other than the fact that the program isn’t working and that certain files might be missing.

Can anyone point out what the issue is here or make suggestions to find what is causing this issue?
