Description

Hi,
When one creates a new ACID table and inserts data into it using INSERT INTO, Hive does not write a 'base' file : it only creates a delta. That may lead to two issues (at least):

when you try to read it, you might get a 'serious problem' like that :

I do not always get this error, but when I get it, I need to drop/recreate table.

Spark-sql does not see data as long as there is no base file. So as long as compaction has not occurred, no data can be read using Spar-SQL. See https://issues.apache.org/jira/browse/SPARK-16996

I know Hive always creates a base file when ou INSERT OVERWRITE, but you cannot always use OVERWRITE instead of INTO : in my use case, I use a statement that writes data into partitions that already exist and partitions that do not exist yet.
