> Issue Type: New Feature
> Affects Versions: trunk
> Reporter: Robert Kanter
> Assignee: Robert Kanter
>
> When a user has a busy cluster and long running coordinator jobs, streaming
> the logs can be really slow. In this situation, the user is typically only
> interested in the latest logs and doesn't care about logs from a while ago.
> So, we can speed this up by adding a parameter or something to the log
> streaming API to only fetch the logs from the last x hours. The log files
> roll over every hour, so this should be pretty straightforward. We can also
> prepend a message to the logs streamed back mentioning that only the last x
> hours of logs are included. The existing way of getting all of the logs
> should remain unaffected and still work.
