> Provide stage resource information via REST API
> -----------------------------------------------
>
> Key: AMBARI-8163
> URL: https://issues.apache.org/jira/browse/AMBARI-8163
> Project: Ambari
> Issue Type: New Feature
> Components: ambari-server
> Affects Versions: 2.0.0
> Reporter: Robert Levas
> Assignee: Tom Beerbower
> Labels: api, resources, rest_api
> Fix For: 2.0.0
>
>
> Currently, it is possible to query Ambari (via the REST API) for details
> about _asynchronous_ requests and their related tasks. This useful when
> trying to obtain progress information. However, some information necessary
> for the UI to indicate meaningful progress is not available. This
> information is related to the stages that are generated.
> *NOTE:* Each _asynchronous_ request is broken down into 1 or more stages and
> each stage contains 1 or more tasks.
> If stage information was available via the REST API, it would be possible for
> the caller (maybe a UI) to track high-level tasks (at the {{stage}} level)
> rather than each lower-level unit of work (at the {{task}} level).
> To allow for this, a new API resource (and associated handler) needs to be
> created. The resource should be read-only (like {{requests}} and {{tasks}}),
> and should provide information stored in the {{stage}} table from the Ambari
> database.
> The following properties should be returned for each {{stage}}:
> * stage_id
> * request_id
> * cluster_id
> * request_context
> ** _This should probably be renamed to something more appropriate, like
> stage_context, stage_name, or etc..._
> * start_time
> * end_time
> * progress_percent
> * status
> It is expected that the resources would be queried using:
> {code}
> GET /api/v1/clusters/{clusterid}/requests/{requestid}/stages
> {code}
> Also, some subset of the stage data should be provided when querying for
> details about a specific {{request}}, like in:
> {code}
> GET /api/v1/clusters/{clusterid}/requests/{requestid}
> {code}
> See {{request}} and {{task}} resource for examples.
