[jira] [Created] (HIVE-21448) Insert Overwrite of a full ACID table
when the select returns no data is not creating an empty base dir.
Abhishek Somani created HIVE-21448:
--------------------------------------
Summary: Insert Overwrite of a full ACID table when the select returns no data is not creating an empty base dir.
Key: HIVE-21448
URL: https://issues.apache.org/jira/browse/HIVE-21448
Project: Hive
Issue Type: Bug
Components: Transactions
Reporter: Abhishek Somani
{code:java}
insert overwrite table dest_acid select * from src;
{code}
If src has no data, we should still create an empty base directory in dest_acid so that readers get no data to read. This is not happening right now as we do not create such an empty base dir.
Is my understanding correct [~ekoifman] [~gopalv] [~vgumashta] ?
