In the Vertica 7.2.x HTML documentation, It appears that every page under the "Extending Vertica" section is a dead link.
Example links:
https://my.vertica.com/docs/7.2.x/HTML/index.htm#Authoring/ExtendingHPVertica/ExtendingHPVertica.htm
https://my.vertica.com/docs/7.2.x/HTML/index.htm#Authoring/ExtendingHPVertica/Java/JavaDataTypes.htm
For example, if you navigate to any of the preceding links, the documentation header and left nav bar load successfully, but the frame supposed to contain the relevant content instead displays an error message like the following:
Not Found
The requested URL /docs/7.2.x/HTML/Content/Authoring/ExtendingHPVertica/Java/JavaDataTypes.htm was not found on this server.
