Component/s: (was: Web UI)
Spark Shell
> ConsoleProgressBar timer thread leaks SparkContext
> --------------------------------------------------
>
> Key: SPARK-5848
> URL: https://issues.apache.org/jira/browse/SPARK-5848
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Affects Versions: 1.2.1
> Reporter: Matt Whelan
>
> ConsoleProgressBar starts a timer. This creates a thread (which is a garbage
> collection root) with a reference to the ConsoleProgressBar instance, which
> holds a reference to the SparkContext.
> That timer is never canceled, so SparkContexts are leaked.
