Description

If there is a failure on any host during one of the upgrade steps , paused upgrade wizard at "finalize upgrade pre checks" shows incorrect hosts count (0) in the message.

Please see attached screenshot. datanode upgrade failed on one of the hosts. But still upgrade wizard says .
"Upgrade did not succeed on 0 hosts"
And on clicking 0 Hosts, following error is seen in console.
Expected behaviour is - message should have shown 1 hosts and on clicking , failed hosts should have been displayed.
