> * Support for applying a {{WHERE}} clause in {{SHOW PARTITIONS}} was introduced in IMPALA-14065. However, the implementation was scoped only to HDFS-backed tables, and Iceberg support was deferred for a follow-up Jira.
> * The core reason is architectural: Iceberg stores partition metadata in {*}manifest files{*}, not in filesystem directory structures as HDFS tables do.
> * Currently, running {{SHOW PARTITIONS WHERE}} against an Iceberg table results in the following analysis exception:
> {code:java}
> WHERE clause in SHOW PARTITIONS is only supported for HDFS tables {code}
