    Description

      NameNode works properly on IPv4 or IPv6 single stack (assuming in the latter case that scripts have been changed to disable preferIPv4Stack, and dependent on the client/data node fix in HDFS-8078). On dual-stack machines, NameNode listens only on IPv4 (even ignoring preferIPv6Addresses being set.)

      Our initial use case for IPv6 is IPv6-only clusters, but ideally we'd support binding to both the IPv4 and IPv6 machine addresses so that we can support heterogenous clusters (some dual-stack and some IPv6-only machines.)
