Kay Ousterhout created SPARK-1965: ------------------------------------- Summary: Spark UI throws NPE on trying to load the app page for non-existent app Key: SPARK-1965 URL: https://issues.apache.org/jira/browse/SPARK-1965 Project: Spark Issue Type: Bug Components: Web UI Affects Versions: 1.0.0 Reporter: Kay Ousterhout Priority: Minor
If you try to load the Spark UI for an application that doesn't exist: sparkHost:8080/app/?appId=foobar The UI throws a NPE. The problem is in ApplicationPage.scala -- Spark proceeds even if the "app" variable is null. We should handle this more gracefully. -- This message was sent by Atlassian JIRA (v6.2#6252)
