> PROBLEM: Currently if the upgrade is not finalized the balancer just exits as it cannot
move any blocks as no deletes can go through the datanodes before a finalize. This is not
clear to users.
> EXPECTED BEHAVIOR:
> Balancer should exit saying something like "Balancer exiting as upgrade is not finalized.
Please finalize the hdfs upgrade before running the balancer"
