> An action is executed on demand. Actions can also be executed as a part of
> some other operation being executed by Ambari. For example, ‘Verify Kerberos
> Setting’ can be executed while setting up the secured cluster or at a later
> point when the admin has a need to verify the setting while debugging some
> issue.
> Once an action is requested by posting the request to the cluster specific
> actions collection, the executor can monitor the status to know when the
> action has finished execution. The links specific to the hosts can be
> monitored for progress on specific hosts.
> Ambari Server may execute the action on all hosts in parallel.
> A custom action execution request consists of:
> * ActionName: This is a reference to the action being executed
> * Inputs: The inputs provided by the action executor to the action
> * TargetHosts: The set of hosts where the action should be executed
> *API support for Custom Action Execution*
> An action is scheduled by posting a request resource.
> {code}
> curl -u admin:admin -X POST -d'{"RequestInfo":{"context":"Execute an action",
> "action" : "a1", "service_name" : "HDFS", "component_name":"DATANODE",
> "hosts":"h1"}}' http://localhost:8080/api/v1/clusters/c1/requests
> {code}
> Sub-tasks:
> * API support to post action execution
> * API support to read executed actions
> * DB changes to hold action execution requests
