Dmitriy Fingerman updated HIVE-28785:
-------------------------------------
Description:
Hive has code occurences as following:
{code:java}
InetAddress.getByName(String){code}
* Only returns {*}one IP address{*}, even if multiple (IPv4 and IPv6) exist.
* May return an IPv4 address even when an IPv6 address is preferred.
Safer Alternative:
Use InetAddress.getAllByName(hostname) to get all possible addresses and
explicitly choose an IPv6 one if needed.
was:
Hive has code occurences as following:
{code:java}
InetAddress.getByName(String){code}
Issue: This method may return only an IPv4 address if the system is not
properly configured.
Fix: Use InetAddress.getAllByName(String) to support both IPv4 and IPv6.
// Bad - may return only IPv4 address
{code:java}
InetAddress address = InetAddress.getByName("example.com");{code}
// Good
{code:java}
InetAddress[] addresses = InetAddress.getAllByName("example.com");
for (InetAddress addr : addresses) {
System.out.println(addr.getHostAddress());
}{code}
> Fix InetAddress.getByName is not safe with IPv6 stack
