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}
