Description

HDDS-922 added a filtered class loader with a list of delegated classes that will be loaded with the app launcher's classloader. With security enabled on ozone-0.4, there are some incompatible changes from Hadoop-common and hadoop-auth module from Hadoop-2.x to Hadoop-3.x. Some examples can be seen HDDS-1080, where the fix has to be made along with a rebuild/release. 

 

This ticket is opened to allow dynamically adding delegated classes or class prefix via environment variable. This way, we can easily adjust the setting in different deployment without rebuild/release.
