echonesis opened a new pull request, #10801: URL: https://github.com/apache/ozone/pull/10801
## What changes were proposed in this pull request? Ozone currently forces `java.net.preferIPv4Stack=true` for daemon processes and Maven test executions. This prevents the JVM from using its default networking behavior and blocks IPv6-capable or dual-stack environments unnecessarily. - Removes the default `java.net.preferIPv4Stack=true` setting from Ozone shell bootstrap. - Removes the corresponding global Surefire system property. - Removes the legacy Linux `net.ipv6.bindv6only` check and the undocumented `OZONE_ALLOW_IPV6` developer override. - Updates `ozone-env.sh` to document that Ozone follows the JVM's default IP stack preference while retaining instructions for operators who need to force IPv4. - Adds Bats coverage verifying that shell bootstrap does not force IPv4 by default and preserves an explicitly configured IPv4 preference. Operators can continue to force IPv4 when required by setting: ```shell export OZONE_OPTS="-Djava.net.preferIPv4Stack=true" ``` Generated-by: Codex (GPT-5) ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-15772 ## How was this patch tested?
