------------------------------------------
Summary: Cleanup IMetaStoreClient#getPartitionsByNames APIs
Key: HIVE-25935
URL: https://issues.apache.org/jira/browse/HIVE-25935
Project: Hive
Issue Type: Task
Components: Metastore
Reporter: Stamatis Zampetakis
Currently the
[IMetastoreClient|https://github.com/apache/hive/blob/4b7a948e45fd88372fef573be321cda40d189cc7/standalone-metastore/metastore-common/src/main/java/org/apache/hadoop/hive/metastore/IMetaStoreClient.java]
interface has 8 variants of the {{getPartitionsByNames}} method. Going quickly
over the concrete implementation it appears that not all of them are
useful/necessary so a bit of cleanup is needed.
Below a few potential problems I observed:
* Some of the APIs are not used anywhere in the project (neither by production
nor by test code).
* Some of the APIs are deprecated in some concrete implementations but not
globally at the interface level without an explanation why.
* Some of the implementations simply throw without doing anything.
* Many of the APIs are partially tested or not tested at all.
HIVE-24743, HIVE-25281 are related since they introduce/deprecate some of the
aforementioned APIs.
It would be good to review the aforementioned APIs and decide what needs to
stay and what needs to go as well as complete necessary when relevant.
