Hello,
The vSphere Big Data Extensions Administrator's and User's Guide listed the wrong URL with which register the plug-in. This has since been corrected, and a new version of the documentation has been uploaded to the Big Data Extensions Documentation forum.
As has been stated above, the correct URL with which to register the Big Data Extensions plug-in is:
http://management-server-ip-address:8080/register-plugin
You can find this correction on page 11 of the vSphere Big Data Extensions Administrator's and User's Guide.
We apologize for any inconvenience this may have caused.
Kind Regards,
Chris Bedford
