[jira] [Comment Edited] (SPARK-21124) Wrong user shown in UI when
using kerberos
[ https://issues.apache.org/jira/browse/SPARK-21124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16052409#comment-16052409 ]

Also, the changes in SPARK-14483 also mask which is the actual user the application running in the cluster (i.e. who actually is reading / writing files).
The thrift server doesn't do per-job impersonation, as far as I know, so it would still be useful to show the kerberos user the application is running as somewhere.

> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 2.2.0
> Reporter: Marcelo Vanzin
> Priority: Minor
>
> When submitting an app to a kerberos-secured cluster, the OS user and the user running the application may differ. Although it may also happen in cluster mode depending on the cluster manager's configuration, it's more common in client mode.
> The UI should show enough information about user running the application to correctly identify the actual user. The "app user" can be easily retrieved via {{Utils.getCurrentUserName()}}, so it's mostly a matter of how to record this information (for showing in replayed applications) and how to present it in the UI.
