James Kinley commented on OOZIE-891:
------------------------------------
I've had another look at this and now remember why I went down the
{{Ext.data.PagingMemoryProxy}} route in the first place.
The top-level tabs for "Workflow Jobs", "Coordinator Jobs", and "Bundle Jobs"
all call the {{V1JobsServlet}}, which appends the required paging tags to the
end of the JSON (e.g. {{"len":5,"offset":2}}).
For example, {{V1JobsServlet#getWorkflowJobs()}} does the following:
{code}
json.put(JsonTags.WORKFLOWS_JOBS, WorkflowJobBean.toJSONArray(jsonWorkflows,
timeZoneId));
json.put(JsonTags.WORKFLOWS_TOTAL, jobs.getTotal());
json.put(JsonTags.WORKFLOWS_OFFSET, jobs.getStart());
json.put(JsonTags.WORKFLOWS_LEN, jobs.getLen());
{code}
Then in {{oozie-console.js}}, the following is added to the corresponding
{{Ext.grid.GridPanel}}'s for paging:
{code}
bbar: getPagingBar(jobActionStatus)
{code}
The difficulty with the popups is that the JSON is returned for individual
workflows|coordinators|bundles by the {{V1JobServlet}} and appending the
required paging tags is not so straight forward.
For example, to get the paging tags in for workflows, {{JsonWorkflowJob}} would
have to be modified to A) take the start and length filters into consideration
in {{toJSONObject()}} and B) know how many actions the workflow has in total
(not just number of filtered actions). It's going to take me a little more time
to work through this.
