Koelli Mungee updated HDFS-9790:
--------------------------------
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"

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 customers as many in the field do not even
understand what an upgrade finalized action does in HDFS.
EXPECTED BEHAVIOR:
Balancer should exit saying something like "Balancer exiting as upgrade is not
finalized. Please finalize the hdfs upgrade before running the balancer"
> HDFS Balancer should exit with a proper message if upgrade is not finalized
