             Summary: StreamInterceptor causes channel to be closed if user 
code throws exceptions
                 Key: SPARK-11930
                 URL: https://issues.apache.org/jira/browse/SPARK-11930
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Marcelo Vanzin
            Priority: Minor


The current implementation of {{StreamInterceptor}} in the network library 
allows user exceptions to bubble up to the network layer, which would cause the 
channel to be closed.

That's fine for the current use cases, but in some cases it might be better to 
swallow the exceptions and ignore any incoming data that is part of the stream, 
keeping the channel open. We should add that option.
