--------------------------
Summary: Lifecycle of RDDs in Cluster envs
Key: SPARK-8134
URL: https://issues.apache.org/jira/browse/SPARK-8134
Project: Spark
Issue Type: New Feature
Components: Spark Core
Affects Versions: 1.3.1
Reporter: sid
Is there a way to implement simple driver lifecycle like this.
init() - connect to JMS
RDD - read a file and pump out messages
close() - close JMS
Currently we are hacking RDDs to create singleton connections (worked node
agnostic); but then unable to close them.
also when i call SparkContext.close(); it immediately kills jobs in worker
nodes.
There is NO WAY of knowing when to close the context in driver
I looked into SparkListener and that doesnt help solve our problem.
I assumed driver would stay alive until jobs are done and cleanup. Driver
simply spawns jobs and ends
