Hi Louis,

Thanks for the explanation. I do know that Unity Catalog is the way to go forward in the future. I just wanted to give an internal training to some new employees and explain them the difference between the old(hive) and the new (UC) of working. 

Last week I did create a new Azure Tenant and a new Databricks account and to my surprise I did not see the legacy hive megastore anymore. If I understand point three in your comment correctly, it means that if the Databricks account is created after December 18, you do not even have the option anymore to reenable the legacy hive metastore ?

Is this new behaviour documented somewhere? I tried searching for I but could not find anything?
