Description

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"
