I want to build Hadoop and Spark cluster over a pure IPv6 environment. I have already built it over IPv4, how can I configure to run them under IPv6 environment？Do hadoop and spark support IPv6 now?
回答1:
It does not. As of today HADOOP-11890, which track progress of IPv6 support, is still unresolved.
