Is it mandatory to disable IPV6 on all the nodes before I give them to the Cloudera Standard?

[#1]

Hi -

I am about to create a 23 node cluster with Cloudera Standard. Is it mandatory to disable IPV6 on all the nodes before I give them to the Cloudera Standard?

Thanks!

No it is not "manditory", but note that hadoop is not going to function on a ipv6 only network right now.

On current linux distro's it is difficult to disable ipv6 completely, you can just leave it as be.  In debian distro's it appears there can be issues, which the abolve hadoop wiki post addresses.

Thank you!

I should have mentioned my OS also in the question. It is Oracle Enterprise Linux 6. I believe it is not IPV6 only. Please correct me if I am wrong.

Nothing is IPv6 only at this point, so you don't have to worry.  Its going to take a while before we (the internets) can do IPv6 only for things.
