---------------------------------------
Summary: Support Iceberg tables in SHOW PARTITIONS WHERE
Key: IMPALA-14555
URL: https://issues.apache.org/jira/browse/IMPALA-14555
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Reporter: Arnab Karmakar
Assignee: Arnab Karmakar
Enable {{SHOW PARTITIONS … WHERE}} support for Iceberg tables.
*Description*
Support for applying a {{WHERE}} clause in {{SHOW PARTITIONS}} was first
introduced in
{*}[IMPALA-14065|{*}{*}[http://issues.apache.org/jira/browse/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}
