Subject [jira] [Updated] (AMBARI-1601) Server level action support
Date Sat, 09 Mar 2013 08:21:12 GMT


Sumit Mohanty updated AMBARI-1601:

    Attachment: AMBARI-ServerAction.patch

This is a prototype to allow synchronous execution of server actions by the action scheduler.
This may be appropriate for simple actions while a design is finalized for async execution
similar to the agents. This implementation also makes use of the host_role_command definition
rather than defining a special server action schema.

> Ambari currently, supports only agent level actions. There is a need to server level
action that allows the server to execute some task as part of a request. Some sample requirements
> * Record the current state of the cluster after upgrade
> * Evaluate cumulative result of several stages
> * Add stages based on the outcome of previous stages
> This feature can be added in phases across several releases. The immediate need is to
update cluster stack version after upgrade is complete.
