Chao Sun updated HIVE-27868:
----------------------------
Description: HIVE-18755 introduced the concept of catalog which adds
another level of namespace on top of tables and databases. Given HMS using Hive
3.x already has this feature and Hive 2.3 client is commonly used to talk to
these metastores through frameworks such as Spark, this JIRA proposes to
backport a subset of the features to allow Hive 2.3 client to specify catalog
to read from the 3.x metastores.
> Backport a subset of HIVE-18755 to branch-2.3 to support reading from catalog
> in HMS 3+
