Sanket Reddy commented on SPARK-24787:
--------------------------------------

[~vanzin] do you have any suggestions regarding this issue?

[~olegd] I would rather make this configurable or trigger periodically?

>                 URL: https://issues.apache.org/jira/browse/SPARK-24787
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core, Web UI
>    Affects Versions: 2.3.0, 2.3.1
>            Reporter: Sanket Reddy
>            Priority: Minor
>
> [https://github.com/apache/spark/pull/16924/files] updates the length of the inprogress
files allowing history server being responsive.
> Although we have a production job that has 60000 tasks per stage and due to hsync being
slow it starts dropping events and the history server has wrong stats due to events being
dropped.
> A viable solution is not to make it sync very frequently or make it configurable.
