Getting Unsupported major minor version error

0 votes

I am trying to write a map-reduce program but I am getting an error as 

"Unsupported major.minor version 52.0".

I realized that I have different Java versions (1.8.0 on main system and 1.7.0 on VM)

My question is: Is it better to upgrade other machines to 1.8 or to downgrade the java version?

I will recommend not to upgrade the Java version in your VM. This is because then we have to make many changes in the .bashrc files as well as the configurations files, where we have to set the Java home path. This might make the VM behave abnormally. It is better to downgrade the Java version. Here are the steps to downgrade: https://www.edureka.co/community/38974/java-version-mismatch
