Jungtaek Lim commented on SPARK-28594:
--------------------------------------

Coincidentally I was working on the design of this feature for 2 weeks. Looks like reporter
doesn't seem to work on this feature, I'll taking up this issue and go forward.

Only POC done. Just started implementing. Here's design doc to describe the approach:

>                 Key: SPARK-28594
>                 URL: https://issues.apache.org/jira/browse/SPARK-28594
>             Project: Spark
>          Issue Type: Improvement
>          Components: Input/Output
>    Affects Versions: 3.0.0
>         Environment: This has been reported on 2.0.2.22 but affects all currently available
versions.
>            Reporter: Stephen Levett
>            Priority: Minor
>
> At all current Spark releases when event logging on spark streaming is enabled the event
logs grow massively.  The files continue to grow until the application is stopped or killed.
> The Spark history server then has difficulty processing the files.
> https://issues.apache.org/jira/browse/SPARK-8617
> Addresses .inprogress files but not event log files that are still running.
> Identify a mechanism to set a "max file" size so that the file is rolled over when it
reaches this size?
