Sam Barker commented on FLINK-35694:
------------------------------------
Why does it switching to {{--all-ip-addresses}} fix this? Is it that it omits
the loopback interfaces or is it just the ordering of IP addresses? I ask as
the man page says not to depend on the order of IP addresses returned.
{quote}-I, --all-ip-addresses
Display all network addresses of the host. This option enumerates
all configured addresses on all network interfaces. The loopback interface
and IPv6 link-local addresses are omitted. Contrary to option
-i, this option does not depend on name resolution. Do not make any assumptions
about the order of the output.{quote}
