      Description

      The JDBC PreparedStatement interface extends Statement interface. The Hive JDBC driver implementations of HivePreparedStatement interface is disjoint from the HiveStatement implementation. As a result there's some duplicate code in these two classes for executing query. Also patches like implicit close on re-execute etc. are not there for PreparedStatement.

      The HivePreparedStatement should extend the HiveStatement.
