Robert Joseph Evans commented on MAPREDUCE-3971:
------------------------------------------------
Bhallamudi,
I agree that there are a number of optimizations that can be made and that we
can guarantee ordering if we do them correctly. I am just not positive what
those optimizations should be yet. I made a proposal on MAPREDUCE-3973 to
possibly change the back end all together. If you have feedback on it I would
be very grateful to hear it. Depending on how that proposal is received the
way this JIRA is implemented could be very different.
> Job History web services need to have limits on the number of itmes they can
> return.

> The Job History web services canput a very large load on the job history
> server. We should put in a limit on the number of entries that can be
> returned by the web service, and also add in the ability to modify the
> starting location in the list, so that all entries can still be downlaoded.
> Just not all at once.
