Subject: Re: Any way to reset Ambar= i Install Wizard?

try to restart ambari server and agents, then stop and sta= rt services, sometimes services need to announce themselves to Ambari that = they're installed. Always refer to the ambari-server log. Worst case scenar= io, delete Ambari_metrics service with API and clean up the postgres DB manually, tables to concentrate on a= re hostservicedesiredstate, servicedesiredstate etc. This should be last re= sort.

Some manual update in DB is most likely needed.

*WARNING* use this at your own risk

The table that needs to be updated is cluster_version.

As far as I tested 2.1, it required less manual intervention than 2.0.= 1. Upgrade has a retry button for most of the steps, and this is really coo= l.

Hope this help.

Hello,

I upgraded a small test cluster from HDP 2.1 to HDP 2.2 and Ambari 2.0= .1. In following the steps to replace Nagios + Ganglia with the Ambari = Metrics System using the Ambari Wizard, an install failure occurred on one = node due to an outdated glibc library. I updated glibc and verified the Metrics packages could be installed, but = couldn=92t go back and finish the installation through the wizard. The prob= lem is: it flags some of the default settings, saying they need to be chang= ed, but it skips past the screen very quickly that enables those settings to be changed, without allowing anythi= ng to be entered. So the button that allows you to proceed with the install= ation never becomes enabled.

I subsequently manually finished the Metrics installation using the Am= bari API and have it running in Distributed mode. But Ambari=92s wizard can= not be used for anything now: the same problem= described above occurs for every service I try to install.

Can Ambari be reset somehow in this situation, or do I need to reinsta= ll it?
Or do you recommend installing 2.1?

Thanks
Ken
