> Key: SPARK-5771
> URL: https://issues.apache.org/jira/browse/SPARK-5771
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.2.1
> Reporter: Liangliang Gu
> Priority: Minor
> Fix For: 1.4.0
>
>
> In Standalone mode, the number of cores in Completed Applications of the
> Master Web Page will always be zero, if sc.stop() is called.
> But the number will always be right, if sc.stop() is not called.
> The reason maybe:
> after sc.stop() is called, the function removeExecutor of class
> ApplicationInfo will be called, thus reduce the variable coresGranted to
> zero. The variable coresGranted is used to display the number of Cores on
> the Web Page.
