When creating a component with the Repository connection, like tHDFSConnection the Hadoop properties do automatically show up in the Hadoop Properties table as one would expect. However the all the context variables in the Value column are quoted. They are context variables at this point and not text so should not be quoted. Removing the quotes allows jobs to work correctly, however then the connection Property Type changes from Repository to Built-In. This negates much of the point of using a repository connection.
