[PR] Docs: Document default-namespace limitation with SparkSessionCatalog [iceberg]
wombatu-kun opened a new pull request, #16591:
URL: https://github.com/apache/iceberg/pull/16591
## Summary
Closes #14424.
`spark.sql.catalog.spark_catalog.default-namespace` has no observable effect when used with `SparkSessionCatalog`. Spark initializes the session catalog's current namespace from its built-in V1 `SessionCatalog`, which bypasses the V2 catalog's `defaultNamespace()`. The current docs list `default-namespace` under "Common configuration properties" without flagging this gap, which led the reporter to expect it to work.
This PR adds a note in the "Replacing the session catalog" section pointing users to Spark's `spark.sql.catalog.spark_catalog.defaultDatabase` instead, which the reporter confirmed works as a workaround.
