[SPARK-19970][SQL] Table owner should be USER instead of PRINCIPAL in
kerberized clusters
## What changes were proposed in this pull request?
In the kerberized hadoop cluster, when Spark creates tables, the owner of
tables are filled with PRINCIPAL strings instead of USER names. This is
inconsistent with Hive and causes problems when using ROLE in Hive. We had
better to fix this.
**BEFORE**
```scala
scala> sql("create table t(a int)").show
scala> sql("desc formatted t").show(false)
...
|Owner: |sp...@example.com
| |
```
**AFTER**
```scala
scala> sql("create table t(a int)").show
scala> sql("desc formatted t").show(false)
...
|Owner: |spark
| |
```
## How was this patch tested?
Manually `create table` and `desc formatted` because this happens in
Kerberized clusters.
