Hive insert and ACID

[#1]

Hi,

I created a simple Hive table (everything default) and were surprised that I could insert data into it doing INSERT INTO TABLE etc.

The Hive manual claims that insert is available only for tables that support ACID. However, I didn't set anything to enable ACID support for my table. Also, data is not in ORC.

Can you please explain this behavior ?

Thanks

Thanks Eugene. I will remove my answer.

Thanks @Eugene Koifman

Can you point to an updated complete and updated documentation/book on Hive features ? (ACID, LLAP, etc)
