   > Alex, why would we allow such a verification to be bypassed, do you have 
some real world use case for this ?
   
   You could find yourself in the situation where the catalog server has TLS 
enabled, and its certificate shows a SAN of e.g. `catalog.bigcorp.com`; but if 
the client/engine is in the same cluster/network, it could actually be 
contacting the catalog through its internal IP instead, e.g. 
`https://1.2.3.4:8181/api/catalog`. In that case, the hostname verification 
will fail.
    
   (Please note: I mentioned `NoopHostnameVerifier` just as an example of 
possible usage of `HostnameVerificationPolicy`.)
