Saisai Shao commented on SPARK-21521:
-------------------------------------

I I think we should have a special logics to treat special users like "root", in the current
logics we don't have such logics and treat "root" as a normal user, that's why it will be
failed in this case.

>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 2.2.0

> (Regression cf. 2.0.2)
> We run spark as several users, these write to the history location where the files are
saved as those users with permissions of 770 (this is hardcoded in EventLoggingListener.scala).
> The history service runs as root so that it has permissions on these files (see https://spark.apache.org/docs/latest/security.html).
> This worked fine in v2.0.2, however in v2.2.0 the events are being skipped unless I add
the root user into each users group at which point they are seen.
> We currently have all acls configuration unset.
