IMPALA-9935: Support individual partitions in catalog_object webUI page
This patch adds support for querying individual partition metadata through
the /catalog_object webUI endpoint on both CatalogServer and Coordinator.
Previously, the endpoint only supported DATABASE, TABLE, VIEW, FUNCTION,
DATA_SOURCE, HDFS_CACHE_POOL, PRINCIPAL, PRIVILEGE, and
AUTHZ_CACHE_INVALIDATION catalog object types. This change adds support
for HDFS_PARTITION objects.
Endpoint Availability:
- Catalog V1 (legacy catalog mode): Works on both CatalogServer
(port 25020) and Coordinator (port 25000)
- Catalog V2 (local catalog mode): Only works on CatalogServer (port 25020)
URL Examples:
- Basic:
/catalog_object?object_type=HDFS_PARTITION&object_name=mydb.mytable%3Ayear%3D2010%2Fmonth%3D3
- Multi-key:
/catalog_object?object_type=HDFS_PARTITION&object_name=db.tbl%3Ayear%3D2024%2Fmonth%3D12%2Fday%3D25
- Special chars:
/catalog_object?object_type=HDFS_PARTITION&object_name=db.tbl%3Ads%3D2024%252F12%252F25
Testing:
- Existing tests pass
- New tests added for partition object retrieval in both HTML and JSON formats
- Manual testing with various partition configurations
- Error handling tested for edge cases

> URL: https://issues.apache.org/jira/browse/IMPALA-9935
> Project: IMPALA
> Issue Type: New Feature
> Components: Catalog
> Reporter: Quanlong Huang
> Assignee: Arnab Karmakar
> Priority: Major
> Labels: ramp-up
>
> CatalogServer and Coordinator both have a webUI page (/catalog_object) for
> getting catalog objects. An example URL is
> "[http://localhost:25020/catalog_object?object_type=TABLE&object_name=functional.alltypes]";.
> After IMPALA-3127, it'd be nice to support the same feature for individual
> partitions.
> Note that the object_name for partitions are designed as
> dbName+tableName+partitionName in IMPALA-3127. The partitionName part has "/"
> characters, which conflicts in parsing the request arguments in the URL. We
> may need to redesign the arguments for partitions.
