Xiao Li 344f38b04b [SPARK-19970][SQL][FOLLOW-UP] Table owner should be USER instead of PRINCIPAL in kerberized clusters #17311 
### What changes were proposed in this pull request?
This is a follow-up for the PR: https://github.com/apache/spark/pull/17311

- For safety, use `sessionState` to get the user name, instead of calling `SessionState.get()` in the function `toHiveTable`.
- Passing `user names` instead of `conf` when calling `toHiveTable`.

### How was this patch tested?
N/A

Spark SQL

This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.

Spark SQL is broken up into four subprojects:

  • Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
  • Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
  • Hive Support (sql/hive) - Includes an extension of SQLContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs.
  • HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.
