[SPARK-16556] [SQL] Fix Silent Ignorance of Bucket Specification When
Creating Table Using Schema Inference
#### What changes were proposed in this pull request?
When creating a data source table without explicit specification of schema
or SELECT clause, we silently ignore the bucket specification (CLUSTERED BY...
SORTED BY...). For example,
```SQL
CREATE TABLE jsonTable
USING org.apache.spark.sql.json
OPTIONS (
path '${tempDir.getCanonicalPath}'
)
CLUSTERED BY (inexistentColumnA) SORTED BY (inexistentColumnB) INTO 2
BUCKETS
```
This PR captures it and issues an error message.
#### How was this patch tested?
Added a test case in DDLSuite
