> HADOOP-5257 introduced ServicePlugin capabilities for NameNode/DataNode. As
> of now they could be activated by configuration values.
> I propose to activate plugins with Service Provider Interface. In case of a
> special service file is added a jar it would be enough to add the plugin to
> the classpath. It would help to add optional components to NameNode/DataNode
> with settings the classpath.
> This is the same api which could be used in java 9 to consume defined
> services.
