> HDFS NameNode Web UI generates invalid HTTP links for DataNodes in IPv6
> environment
> -----------------------------------------------------------------------------------

> Key: HDFS-17834
> URL: https://issues.apache.org/jira/browse/HDFS-17834
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.4.1
> Environment: !image-2025-09-10-10-12-28-486.png|width=545,height=298!
> Reporter: sunhui
> Priority: Minor
> Labels: pull-request-available
> Attachments: fixwebsite_support_ipv6.diff,

>
>
> In the HDFS NameNode Web UI
> (http://nn-host:9870/dfshealth.html#tab-datanode), the "Http Address" column
> for DataNodes generates completely corrupt and invalid links when the
> DataNode's address is an IPv6 literal.
> 1. It fails to encapsulate the IPv6 address in square brackets `[]`, which is
> required by RFC 2732. 2. More critically, it appears to **parse the IPv6
> address incorrectly**, mistaking a part of the address (e.g., the `30` in
> `1172:30:...`) for the port number, which completely breaks the URL. This
> results in a malformed, unclickable link that does not point to the
> DataNode's web interface. **Current Behavior & Evidence:** The DataNode's
> actual address is: `[1172:30:0:0:0:0:8a34]:50010` However, the NameNode UI
> displays the link as: `https://datanodeHostname:30` This link is **invalid**
> and leads nowhere. The UI has: - Stripped the original port `50010`. -
> Incorrectly extracted `30` (which is part of the IPv6 address) and used it as
> the port. - Failed to wrap the IPv6 address, leading to incorrect parsing.
