> Windows: make preferIPv4Stack overridable, matching hadoop-functions.sh
> -----------------------------------------------------------------------
>
> Key: HADOOP-19935
> URL: https://issues.apache.org/jira/browse/HADOOP-19935
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: scripts
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Labels: pull-request-available
>
> Prompted by HADOOP-16943, I noticed that Windows hadoop-config.cmd still
> disables IPv6.
> On Unix the IPv4 pin has been overridable since HADOOP-9902 (2014):
> hadoop-functions.sh uses
> {{{}$\{HADOOP_OPTS:-"-Djava.net.preferIPv4Stack=true"{}}}}, so setting
> {{HADOOP_OPTS}} selects dual-stack or IPv6. hadoop-config.cmd never matched
> it. It appended the pin unconditionally, so IPv6 could not be enabled on
> Windows at all.
> Proposal: Apply the pin only when {{HADOOP_OPTS}} is unset, mirroring the
> Unix default. IPv4 stays the default when {{HADOOP_OPTS}} is unset; operators
> who set it can now choose dual-stack or IPv6.
