-------------------------------------
Summary: 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.
