> Key: YARN-5571

> Timeline reader provides REST end point for querying app with an URL {{GET
> /ws/v2/timeline/apps/\{app id\}}} along with queryParam as an filter. But
> queryParam such as {{userId/flowname/flowrunid}} not at useful for querying
> an app with app-id. In YARN cluster, only one app-id will be exist though out
> life time. So userId/flowname/flowrunid not at all useful for the app-id REST
> empoint
> {noformat}
> @GET
> @Path("/apps/{appid}/")
> @Produces(MediaType.APPLICATION_JSON)
> public TimelineEntity getApp(
> @Context HttpServletRequest req,
> @Context HttpServletResponse res,
> @PathParam("appid") String appId,
> @QueryParam("flowname") String flowName,
> @QueryParam("flowrunid") String flowRunId,
> @QueryParam("userid") String userId,
> @QueryParam("confstoretrieve") String confsToRetrieve,
> @QueryParam("metricstoretrieve") String metricsToRetrieve,
> @QueryParam("fields") String fields,
> @QueryParam("metricslimit") String metricsLimit) {
> return getApp(req, res, null, appId, flowName, flowRunId, userId,
> confsToRetrieve, metricsToRetrieve, fields, metricsLimit);
> }
> {noformat}
