> Similar to the manner in which the nodemanager webUI displays container logs,
> it would be very useful if the historyserver showed the trailing 4K or so of
> the aggregated logs with a link to see the full log.
> When debugging issues the relevant errors are usually at the end of the log,
> so showing just the last few K can enable quick diagnosis without waiting for
> what can be many megabytes of log data to download.
