Alan Gates resolved HIVE-15189.
-------------------------------
Resolution: Not A Bug
> No base file for ACID table
> ---------------------------
>
> Key: HIVE-15189
> URL: https://issues.apache.org/jira/browse/HIVE-15189
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 1.2.1
> Environment: HDP 2.4, HDP2.5
> Reporter: Benjamin BONNET

> 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 :
> {noformat}
> java.lang.RuntimeException: serious problem

> # 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.
