> Appears to actually stem from code in DataNodeID which assumes it's safe to
> append together (ipaddr + ":" + port) -- which is OK for IPv4 and not OK for
> IPv6. NetUtils.createSocketAddr( ) assembles a Java URI object, which
> requires the format proto://[2401:db00:1010:70ba:face:0:8:0]:50010
> Currently using InetAddress.getByName() to validate IPv6 (guava
> InetAddresses.forString has been flaky) but could also use our own parsing.
> (From logging this, it seems like a low-enough frequency call that the extra
> object creation shouldn't be problematic, and for me the slight risk of
> passing in bad input that is not actually an IPv4 or IPv6 address and thus
> calling an external DNS lookup is outweighed by getting the address
> normalized and avoiding rewriting parsing.)
> Alternatively, sun.net.util.IPAddressUtil.isIPv6LiteralAddress()

> This one has existing parsing logic which needs to shift to the last colon
> rather than the first. Should also be a tiny bit faster by using lastIndexOf
> rather than split. Could alternatively use the techniques above.
