Subject [jira] [Commented] (AMBARI-6646) Ability to set rack awareness
Date Thu, 23 Jul 2015 12:57:05 GMT


Ha Son Hai commented on AMBARI-6646:

I have just upgraded to Ambari 2.1 from 2.0.1 after the announcement of HDP 2.3 ready for
The upgrading of Ambari and Ambari Metrics is very easy and smooth. However, after the upgrading,
Ambari display the icon to refresh the services with stale config. I tried to restart the
services, but all of them failed with the error:

Caught an exception while executing custom service command: <class ‘ambari_agent.AgentException.AgentException’>:
‘Broken data in given range, expected – m-n or m, got : /default-rack:0-21′; ‘Broken
data in given range, expected – m-n or m, got : /default-rack:0-21′

I wonder if the error is come from this new feature “rack-awareness”?

P.S. I have 22 servers, all of them running HDP version

> -  Ability to set/edit Rack ID on hosts (On the hosts details page and prob need a dialog
"Manage Rack Assignment..." on the Hosts Action menu to allow you to add Rack IDs and bulk
move hosts in/out of a rack – similar to host config groups dialog)
> -  Adjust heatmap to layout hosts by Rack ID (or default rack if not set)
> -  Adjust hosts table to include Rack ID as a column, which is sortable and searchable
> Ambari will generate a topology script that echos this Rack ID, and sets that topology
script in the config.
