Description

      ResultSet res = stmt.executeQuery(versionQuery);
      if (!res.next()) {
        throw new HiveMetaException("Didn't find version data in metastore");
      }
      String currentSchemaVersion = res.getString(1);
      metastoreConn.close();

When HiveMetaException is thrown, metastoreConn.close() would be skipped.
stmt is not closed upon return from the method.
