Arnab Karmakar updated IMPALA-14555:
------------------------------------
Description:
* 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}
was:
Enable {{SHOW PARTITIONS … WHERE}} support for Iceberg tables.
