Continuing this thread beyond standalone - onto clusters, does anyone have experience successfully
running any Spark cluster on IPv6 only (not dual stack) machines? More companies are moving
to IPv6 and some such as Facebook are only allocating new clusters on IPv6 only network, so
this is getting more relevant.

YARN still doesn’t support IPv6 per

Facebook are doing work on IPv6, which they are clearly using in-house

Nobody has been reviewing that work, but we should. For most people you can just say "don't
use ipv6", but FB have probably run out of IP addrs somewhere and are stuck unless they buy
HP for the two Class-A subnets it holds.

If people were to play with those patches on IPv6, it could make it into Hadoop 2.8
