>
> Webhcat "jobs" api gets the list of jobs from RM and then gets details from
> history server.
> RM has a policy of retaining fixed number of jobs to accommodate for the
> memory it has, while HistoryServer retains jobs based on their age. As a
> result, jobs that RM returns might not be present in HistoryServer and can
> result in a failure. HistoryServer also ends up retrying on failures even if
> they happen because the job actually does not exist.
> The retries to get details from HistoryServer in such cases is too aggressive.
