Nate Edel created HDFS-8271: ------------------------------- Summary: NameNode should bind on both IPv6 and IPv4 if running on dual-stack machine and IPv6 enabled Key: HDFS-8271 URL: https://issues.apache.org/jira/browse/HDFS-8271 Project: Hadoop HDFS Issue Type: Improvement Components: namenode Reporter: Nate Edel Assignee: Nate Edel
NameNode works properly on IPv4 or IPv6 single stack (assuming scripts have been changed to disable preferIPv4Stack). On dual-stack machines, NameNode listens only on IPv4 (even ignoring preferIPv6Addresses.) Our initial use case for IPv6 is IPv6-only clusters, but ideally we'd support binding to both the IPv4 and IPv6 machine addresses so that we can support heterogenous clusters (some dual-stack and some IPv6-only machines.) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
