Package org.apache.flink.runtime.security.modules

Class JaasModule

java.lang.Object

org.apache.flink.runtime.security.modules.JaasModule

All Implemented Interfaces:

SecurityModule

@Internal
public class JaasModule
extends Object
implements SecurityModule

Responsible for installing a process-wide JAAS configuration.

The installed configuration combines login modules based on: - the user-supplied JAAS configuration file, if any - a Kerberos keytab, if configured - any cached Kerberos credentials from the current environment

The module also installs a default JAAS config file (if necessary) for compatibility with ZK and Kafka. Note that the JRE actually draws on numerous file locations.
