-------------------------------------------
is there an API in ambari-server that we can hit to restart ambari-agent?
> Hosts emit : Host Role Invalid State

> Affects Versions: 1.6.0
> Reporter: Deepak Kumar V
> Priority: Critical

> 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.
