[jira] [Commented] (MAPREDUCE-6422) Add REST API for getting all attempts for all the tasks

["Ray Chiang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14610549#comment-14610549 ] 

Ray Chiang commented on MAPREDUCE-6422:
---------------------------------------

For all job/task related queries, I'd recommend being able to specify a range of what to return (as already recommended in MAPREDUCE-3971).  This has two benefits:

1) You could break queries into smaller chunks of data.  Some of the queries would take too long otherwise.

2) This could also open the door for a more responsive web UI that isn't part of the particular server (e.g. RM, JHS)

> Web UI has the feature where one can get all attempts for all map tasks or reduce tasks. 
> REST api seems to be missing it. 
> Should we add this in both HsWebService and AMWebService ?
> {code}
>   @GET
>   @Path("/mapreduce/jobs/{jobid}/tasks/attempts")
>   @Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
>   public JobTaskAttemptsInfo getAllJobTaskAttempts(@Context HttpServletRequest hsr,
>    @PathParam("jobid") String jid, @QueryParam("type") String type) {
> }
> {code}
> We might also add queryparam on state to filter by succeeded attempts etc.
> Thoughts ?
