We still need to resolve the case sensitivity issues in
[`checkDuplication`](https://github.com/apache/spark/blob/6d86403d8b252776effcddd71338b4d21a224f9b/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/rules.scala#L159-L166).
To reproduce the issue, below is the SQL
```
sql("CREATE TABLE tbl(A int) PARTITIONED BY (a string)")
```
Below is the error we got:
```
org.apache.hadoop.hive.ql.metadata.HiveException:
org.apache.hadoop.hive.ql.metadata.HiveException: at least one column must be
specified for the table
at org.apache.hadoop.hive.ql.metadata.Hive.createTable(Hive.java:720)
```
