Subject [jira] [Commented] (AMBARI-6690) Hosts emit : Host Role Invalid State
Date Tue, 05 Jan 2016 16:40:39 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-6690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15083333#comment-15083333

Dave Beckett commented on AMBARI-6690:
--------------------------------------

I got this issue with ambari 2.1.0 where HCAT was stuck in INSTALL_FAILED despite being installed
and a restart of ambari-agent didn't work for me.  

I did the following fix via  the database so if anyone else needs a workaround until the code
can handle it, this is what I did (mysql):

{{use ambari;}}

{{select host_id from hosts where host_name='HOSTNAME';}}

this gives me the host_id I need e.g. HOSTID

{{update hostcomponentstate set current_state='INSTALLED' where current_state='INSTALL_FAILED'
and host_id=HOSTID;}}

Afterwards I did an 'install clients' from the UI and 'refresh configs' to try to make sure
the install state was reflected.

> 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.
