> 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
> Priority: Major
> Fix For: 4.0.0-alpha-1
>
>
> 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.
