Subject [jira] [Commented] (AMBARI-1601) Server level action support
Date Tue, 12 Mar 2013 02:59:13 GMT


Siddharth Wagle commented on AMBARI-1601:

I think we should define role as AMBARI_SERVER_ACTION, since AMBARI_SERVER is atual Host Role
that we are not using.

Consider separate ThreadPoolExecutor for server-sire tasks, we can have 3 -5 managed threads
for server actions at any point in time.

> 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.
