---------------------------------
Summary: Introduce service provider pattern for user to
dynamically load SecurityFactory classes
Key: FLINK-11589
URL: https://issues.apache.org/jira/browse/FLINK-11589
Project: Flink
Issue Type: Sub-task
Components: Security
Reporter: Rong Rong
Assignee: Rong Rong
Currently there are only 3 security modules in Flink - Hadoop, Zookeeper and
JaaS, all of which are pre-loaded to the Flink security runtime with one
hard-coded path for instantiating SecurityContext, which is used invoke use
code with PrivilegedExceptionAction.
We propose to introduce a [service provider
pattern|https://docs.oracle.com/javase/tutorial/ext/basics/spi.html] to allow
users to dynamically load {{SecurityModuleFactory}} or even introduce a new
{{SecurityContextFactory}} so that all the security runtime context can be set
by dynamically loading any 3rd party JAR. and discover them through property
configurations.
This is especially useful in a corporate environment where proprietary security
technologies are involved.
