Thanks a lot, Daryn.
Do you have any JIRA issue for this work?
It would be nice to work on this.
Regards

Hi Marcos,
Hadoop won't work in a pure IPv6 environment. Hadoop might work in a IPv4/IPv6
environment since the default is to prefer IPv4 addresses. It also might work
if they are publishing IPv4 addrs over IPv6.
The main problem is that hadoop heavily relies on strings containing "ip:port".
The string is naively parsed to split on the first colon which obviously isn't going to
work on IPv6 addresses since they contain colons.
Awhile back I updated some common apis with IPv6 support in mind -- the support
isn't complete though. Bad news: there are quite a number of places throughout
hadoop not using the apis. Good news: For other reasons, I'm currently fixing
many of those places to use the apis. After that work is complete, enabling
IPv6 support might be within relatively easy to moderate reach.

I'm very interested to know if Apache Hadoop works with IPv6 hosts. One
of my clients
has some hosts with this feature and they want to know if Hadoop
supports this.
Anyone has tested this?
Best wishes
