Stas Levin created SPARK-15227:
----------------------------------
Summary: InputStream stop-start semantics + empty implementations
Key: SPARK-15227
URL: https://issues.apache.org/jira/browse/SPARK-15227
Project: Spark
Issue Type: Improvement
Components: Input/Output, Streaming
Affects Versions: 1.6.1
Reporter: Stas Levin
Priority: Minor
Hi,
Seems like quite a few InputStream(s) currently leave the start and stop
methods empty.
I was hoping to hear your thoughts on:
1. Whether there were any particular reasons to leave these methods empty ?
2. Do the stop/start semantics of InputStream(s) aim to support pause-resume
use-cases, or is it a one way ticket?
A pause-resume kind of thing could be really useful for cases where one wishes
to load new offline data for the streaming app to run on top of, without
restarting the entire app.
Thanks a lot,
Stas
