---------------------------------------------
Summary: Ambari starts NN with incorrect flag during upgrade
Key: AMBARI-25438
URL: https://issues.apache.org/jira/browse/AMBARI-25438
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.7.3
Reporter: amarnath reddy pappu
Steps to reproduce:
# Install Ambari 2.6.x and HDP 2.6.x
# enable NN HA
# Upgrade Ambari 2.7.x
# Now Start HDP upgrade to 3.x and after HDFS upgrade is done if you attempt
to re-start Namenode outside of Upgrade flow ( Pause Upgrade) then Ambari would
attempt to start the NN with "–upgrade flag"
# If so it fails to come up with below exception.

Ambari should check if NN upgrade is already done - if it is done already then
it should not check start "upgrade" flag.
