Jacek Lewandowski created SPARK-3883:
----------------------------------------
Summary: Provide SSL support for Akka and HttpServer based
connections
Key: SPARK-3883
URL: https://issues.apache.org/jira/browse/SPARK-3883
Project: Spark
Issue Type: Story
Components: Spark Core
Reporter: Jacek Lewandowski
Spark uses at least 4 logical communication channels:
1. Control messages - Akka based
2. JARs and other files - Jetty based (HttpServer)
3. Computation results - Java NIO based
4. Web UI - Jetty based
The aim of this feature is to enable SSL for (1) and (2).
Why:
Spark configuration is sent through (1). Spark configuration may contain
sensitive information like credentials for accessing external data sources or
streams. Application JAR files (2) may include the application logic and
therefore they may include information about the structure of the external data
sources, and credentials as well.
