Datanodes starting under jsvc are now getting this exception:

When the datanode is using jsvc it's setting a connector but not an endpoint.
The endpoint check added in this patch makes the builder fail for that scenario.

> Currently HttpServer listens to HTTP port and provides a method to allow the
> users to add an SSL listeners after the server starts. This complicates the
> logic if the client needs to set up HTTP / HTTPS serverfs.
> This jira proposes to replace these two methods with the concepts of listener
> endpoints. A listener endpoints is a URI (i.e., scheme + host + port) that
> the HttpServer should listen to. This concept simplifies the task of managing
> the HTTP server from HDFS / YARN.
