[jira] [Commented] (AMBARI-6690) Hosts emit : Host Role Invalid
State
[ https://issues.apache.org/jira/browse/AMBARI-6690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14502600#comment-14502600 ]
Zoltán Marić commented on AMBARI-6690:
--------------------------------------
Hello! I just experienced this problem using Ambari 2.0.0. All my hosts were shut down (the physical machines, including the ambari server). I started them all at the same time. All of the services were in a warning state and restarting them in the Ambari gave this error (host role invalid state).
Running {{sudo ambari-agent}} didn't resolve the problem.
The hosts are in a network with dhcp and their IP addresses may and do change when the machines are restarted (their host names are preserved).

> Key: AMBARI-6690
> URL: https://issues.apache.org/jira/browse/AMBARI-6690
> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 1.6.0
> Reporter: Deepak Kumar V
> Priority: Critical
> Labels: ambari-client, ambari-web
> Fix For: 2.1.0
>
>
> At times hosts move to Invalid state and restart of components throw "Host role in invalid state".
> One way to fix this issue is to ssh into the hosts and run ambari-agent restart
> http://hortonworks.com/community/forums/topic/host-role-in-invalid-state/
> Ambari web interface being single point to manage cluster must provide option to restart ambari-agent. It looses its purpose if one has to manually ssh into the hosts.
