      Description

      I've noticed that the file hive-schema-0.10.0.mysql.sql is creating table SDS with following column:

        `IS_STOREDASSUBDIRECTORIES` bit(1) NOT NULL,
      

      However the upgrade script 011-HIVE-3649.mysql.sql will create the column differently:

      ALTER TABLE `SDS` ADD `IS_STOREDASSUBDIRECTORIES` bit(1) ;
      

      Thus user will get slightly different schema each time - once with "NOT NULL" and secondly with "NULL" definition.
