Unable to generate the bridge model json

The documentation for the Squoop bridge says :
"The default Sqoop modelling is available in org.apache.atlas.sqoop.model.SqoopDataModelGenerator"

This file does not exist in the source tree. The generators are mentioned in the docs but are not there for Hive or Falcon.

I notice that the json model files are generated files. The docs implies that SqoopDataModelGenerator and the like should be used to generate these json model files. Unless I am missing something - it appears that either the docs are incorrect or the source files are missing.
