Review request for Ambari and Dmitro Lisnichenko.
Bugs: AMBARI-9923
https://issues.apache.org/jira/browse/AMBARI-9923
Repository: ambari
Description
-------
Build #1082
1) Enabled NN HA and RM HA. Went to perform upgrade.
2) Seeing this exception in ambari-server.log as soon as I click Perform
Upgrade.
3) The RU dialog has a spinner indefinitely until I close it and reopen, then
finally I have the option to proceed/downgrade
* Please do not print exceptions to Ambari log in INFO scenarios. It makes it hard to troubleshoot when other things are going wrong.
* If this is a real error scenario, then perform upgrade should handle it, print to the log as ERROR and not hang the dialog.
