[jira] [Created] (HADOOP-19695) Add dualstack/IPv6 Support to HttpServer2

Ferenc Erdelyi created HADOOP-19695:
---------------------------------------

             Summary: Add dualstack/IPv6 Support to HttpServer2
                 Key: HADOOP-19695
                 URL: https://issues.apache.org/jira/browse/HADOOP-19695
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: hadoop-common
            Reporter: Ferenc Erdelyi



To enable dualstack and IPv6 support, we use
 InetAddress.getAllByName(hostname) to resolve the IP addresses of a host.
When the system property java.net.preferIPv4Stack is set to true, only IPv4 addresses are returned and any IPv6 addresses are ignored, so no extra check is needed to exclude IPv6.
When java.net.preferIPv4Stack is false, both IPv4 and IPv6 addresses may be returned, and any IPv6 addresses will also be added as connectors.
To disable IPv4, you need OS level configuration.
