This error was caused by permission issue for me.

My jar file has the permission rw-r--r-- by default. I changed it to rwx-rwx-rwx through command chmod 777 my_jar.jar. And the error went away.

Most probable causes :

- Incorrect path of the jar.

- Improper permissions on the folder where Hadoop is trying to run the jar file.

Please make sure you have specified the correct path and you have proper directory permissions.
