Description

Users can configure the desired class to use for a given codec via a property like hadoop.security.crypto.codec.classes.aes.ctr.nopadding. However, even though we provide a default value for this codec in core-default.xml, this default is not also done in the code.

As a result, client deployments that do not include core-default.xml cannot resolve any codecs, and get an NPE.
