[SPARK-19970][SQL][BRANCH-2.1] 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](https://cwiki.apache.org/confluence/display/Hive/SQL+Standard+Based+Hive+Authorization)
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: |[email protected]
| |
```
**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 do `create table` and `desc formatted` because this happens in
Kerberized clusters.
