>
> 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"
