Benjamin BONNET created HIVE-15189:
--------------------------------------
Summary: 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 :

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.
