-------------------------------------
Summary: JobProgressListener gets permanently out of sync with
long running job

URL: https://issues.apache.org/jira/browse/SPARK-3882
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 1.0.2
Reporter: Davis Shepherd
A long running spark context (non-streaming) will eventually start throwing the
following in the driver:

The result is that the ui becomes unusable, and the JobProgressListener leaks
memory as the list of "running" jobs continues to grow.
