Remove transactional=false from Table Properties

In CDH 5.x it is possible to create tables with having the property transactional=false set. While this is a no-op setting, if any of your Hive tables explicitly set this, the upgrade process fails.

You must remove 'transactional'='false' from any tables you want to upgrade from CDH 5.x to CDP. 

Alter the table as follows:
ALTER TABLE my_table UNSET TBLPROPERTIES ('transactional');
