----------------------------------
Summary: StreamingContext cannot be completely stopped if the
stop() call is interrupted
Key: SPARK-12001
URL: https://issues.apache.org/jira/browse/SPARK-12001
Project: Spark
Issue Type: Bug
Components: Streaming
Reporter: Josh Rosen
Assignee: Josh Rosen
If {{StreamingContext.stop()}} is interrupted midway through the call, the
context will be marked as stopped but certain state will have not been cleaned
up. Because the stopped flag will be set, subsequent {{stop()}} calls will be
unable to finish stopping the context, preventing any new StreamingContexts
from being created.
We should mitigate this race condition by ensuring that the second {{stop()}}
call is able to clean up the partially-stopped context.
