--------------------------------------
Summary: Replace file server in driver with RPC-based alternative
Key: SPARK-11140
URL: https://issues.apache.org/jira/browse/SPARK-11140
Project: Spark
Issue Type: Sub-task
Components: Spark Core
Reporter: Marcelo Vanzin
As part of making configuring encryption easy in Spark, it would be better to
use the existing RPC channel between driver and executors to transfer files and
jars added to the application.
This would remove the need to start the HTTP server currently used for that
purpose, which needs to be configured to use SSL if encryption is wanted. SSL
is kinda hard to configure correctly in a multi-user, distributed environment.
