------------------------------
Resolution: Duplicate
> HistoryServer caches incomplete App UIs
> ---------------------------------------
>
> Key: SPARK-8275
> URL: https://issues.apache.org/jira/browse/SPARK-8275
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.3.1
> Reporter: Steve Loughran
>
> The history server caches applications retrieved from the {{ApplicationHistoryProvider.getAppUI()}} call for performance: it's expensive to rebuild.
> However, this cache also includes incomplete applications, as well as completed ones —and it never attempts to refresh the incomplete application.
> As a result, if you do a GET of the history of a running application, even after the application is finished, you'll still get the web UI/history as it was when that first GET was issued.
