thswlsqls opened a new issue, #17089:
URL: https://github.com/apache/iceberg/issues/17089
**Apache Iceberg version**
main @ 49b89a8c5
**Query engine**
Flink
**Please describe the bug**
The Flink Python API `CREATE CATALOG` example in `docs/docs/nessie.md`
(lines 94-99) sets the `'type'` key twice in the same properties map:
`'type'='iceberg', 'type'='nessie', ...`. The repo's established convention for
selecting a catalog implementation (`docs/docs/flink.md` lines 189-197) is
`'type'='iceberg'` (fixed Flink catalog factory identifier) plus a separate
`'catalog-type'='<impl>'` key. `nessie.md`'s example is the only one in the
repo that duplicates `type` instead of using `catalog-type`. A prior fix
attempt, PR #12978, proposed exactly this correction but was closed by
stale-bot with no merit objection ("This is not a judgement on the merit of the
PR"); the bug is still present on `main`.
**Steps to reproduce**
Copy the Python snippet from `nessie.md` line 94-99 and run it against a
Flink Table Environment: the duplicate `'type'` key means no `catalog-type` is
ever set, so a Nessie catalog is not created as intended.
**Additional context**
N/A.
