[jira] [Commented] (HADOOP-12122) Fix Hadoop should avoid unsafe

>
> There are a fairly extensive number of locations found via code inspection which use unsafe methods of handling addresses in a dual-stack or IPv6-only world:
> - splits on the first ":" assuming that delimits a host from a port
> - produces a host port pair by appending :port blindly (Java prefers [ipv6]:port which is the standard for IPv6 URIs)
> - depends on the behavior of InetSocketAddress.toString() which produces the above.
> This patch fixes those metaphors that I can find above, and replaces calls to InetSocketAddress.toString() with a wrapper that properly brackets the IPv6 address if there is one.
