Xi Wang commented on AMBARI-6558:
---------------------------------
https://issues.apache.org/jira/browse/AMBARI-4530 is the same problem in
Install Wizard.
So for 'Add host wizard' we need the same function as
https://issues.apache.org/jira/browse/AMBARI-4530.
Results image attached.
Steps to produce this situation:
1. In Add Host Wizard: Add a new host c6407.
2. Stop ambari agent on c6407 after 'Confirm Hosts ' step.
3. Go to 'Install, Test and Start' step and add the newly added host, then the
wizard runs into 'INSTALL FAILED' state as attached addHost-heartbeatlost.png.
At this time, there are two ways to solve the heartbeat_lost problem on c6407:
1) start ambari agent on c6407, then click on 'Retry'
2) click on 'Next', then on Hosts details page of c6407, re-install each
component.
> FE allows add host on host that is in UNKNOWN state (agent was stopped)

> At this point I can perform AddHost and start the wizard. But AddHost will
> eventually fail - although now I see it just waiting.
> We need some form of error indication when host is not lost.
