      Description

      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.
