------------------------------
Summary: Ambari server to print error messages if NN HA namenode
services properties use diff FQDN (dual network cards) than FQDN in the
HostComponentState table
Key: AMBARI-21327
URL: https://issues.apache.org/jira/browse/AMBARI-21327
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: trunk
Reporter: Di Li
Assignee: Di Li
Fix For: trunk
For hosts with dual network cards and configured with two FQDN, it's possible
to manually config NN HA with alternative FQDN than the ones recorded in the
Ambari database. This caused an issue for EU/RU when upon kicking off the
upgrade via UI, the UI immediately posts the following error:
"An internal system exception occurred: Request specifies host XXXXX but it is
not a valid host based on the target service=null and component=null"
