   It turns out that the bulkloader works fine.  There is a different bug in Hop related to classloading where if you use JDBC drivers in an external folder then something bad happens and these kinds of errors appear.  The errors go away on the out of the box Hop as it doesn't try to use external JDBC driver folders.  The safest place I found for JDBC jar files is hop/lib/core.   This was what Bart and I discovered troubleshooting my environment.  It caused errors to come up when I tried the Vertica bulkloader.
   
   There is, however, still a null pointer exception when clicking the SQL button on the Postgres Bulkloader transform, but at least the data transfer functionality works.
