-------------------------------
Summary: Remove HiveClient and setCurrentDatabase from
HiveSessionCatalog
Key: SPARK-17250
URL: https://issues.apache.org/jira/browse/SPARK-17250
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.1.0
Reporter: Xiao Li
This is the first step to clean `HiveClient` from `HiveSessionState`. In the
metastore interaction, we always set fully qualified names when
accessing/operating a table. That means, we always specify the database. Thus,
it is not necessary to use `HiveClient` to change the active database in Hive
metastore.
In `HiveSessionCatalog `, `setCurrentDatabase` is the only function that uses
`HiveClient`. Thus, we can remove it after removing `setCurrentDatabase`
