--------------------------------------
Summary: Throw specific IllegalStateException subtype when that
asserting SparkContext not stopped
Key: SPARK-21081
URL: https://issues.apache.org/jira/browse/SPARK-21081
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.1.1
Reporter: Filipp Zhinkin
Priority: Minor
org.apache.spark.SparkContext.assertNotStopped throws IllegalStateException if
the context was stopped.
Unfortunately, it is not so easy to distinguish IAE caused by a stopped context
from some other failed assertion and handle it properly (start a new context,
for example).
I'm suggesting to add a specific IllegalStateException subclass
(SparkContextClosedException) and start throwing it.
