title: Azure Data Factory Copy Behaviour "Preserve Hierarchy" not working
body: <p>I am trying to copy data from one container in Azure Data lake Gen2 into another in the same Storage Account. I want preserve the same hierarchy with folders and subfolders but whatever I try it does only copy the json file and no folders.</p>
  <p>As of now I have the target container set in the target dataset. Should I add something more (such as directory and file)?</p>
