   Hi @ayushtkn ,
   If we have `java.net.preferIPv4Stack=false` and 
`java.net.preferIPv6Addresses=false` (which is BTW the default in Java), there 
won't be behavior change in Hive because it doesn't make IPv6 preferred over 
IPv4. 
   
   - `java.net.preferIPv4Stack=false` --> makes both IPv4 and IPv6 available 
(when `true`, IPv6 is completely disabled).
   - `java.net.preferIPv6Addresses=false` --> IPv4 addresses are preferred over 
IPv4.
   
   The only time Java would prefer to use IPv6 with these settings is when a 
DNS name has only IPv6 mapping.
   If Hive precommit tests pass with this change on a dual-stack machine, would 
you agree with these changes?
