balodesecurity opened a new pull request, #8419:
URL: https://github.com/apache/hadoop/pull/8419
## Summary
- In `histogram-hostip.js`, `open_hostip_list()` extracted the host from
`dn.infoAddr` using `split(":")[0]`. For an IPv6 `infoAddr` of the form
`[2001:db8::1]:9864` this yields `[2001` instead of the full IPv6 address.
- Fix mirrors the logic already used in `dfshealth.js`: split on `]:` first;
if more than one part the address is IPv6 and we strip the leading `[` from
part `[0]`; otherwise fall back to the original IPv4 `split(":")[0]` path.
## Test
- JavaScript-only change; verified manually that IPv4 (`host:port`)
continues to extract the host, and IPv6 (`[addr]:port`) now correctly extracts
the full address without brackets.
