Class JaasConfiguration

java.lang.Object

javax.security.auth.login.Configuration

org.apache.oozie.util.JaasConfiguration

public class JaasConfiguration
extends Configuration

Creates a programmatic version of a jaas.conf file. This can be used instead of writing a jaas.conf file and setting the system property, "java.security.auth.login.config", to point to that file. It is meant to be used for connecting to ZooKeeper.

example usage: JaasConfiguration.addEntry("Client", principal, keytabFile); javax.security.auth.login.Configuration.setConfiguration(JaasConfiguration.getInstance());
