Aihua Xu commented on HIVE-13050:
---------------------------------
[~lskuff] Yeah, that's a concern that it will introduce the incompatibility.
The only problem is the inconsistency that {{SELECT *}} and {{SELECT
count(*)}} will be inconsistent as the example I listed in the description. We
should be one way or the other, do you agree?

> CREATE TABLE test (s STRING) PARTITIONED BY (p SMALLINT) location
> 'data/test';
> INSERT INTO test PARTITION (`p`=1) VALUES ("v1");
> INSERT INTO test PARTITION (`p`=2) VALUES ("v2");
> ALTER TABLE test PARTITION (`p`=2) SET LOCATION '/data/test/p=1';

> {{select * from test;}} shows 2 rows while {{SELECT count(*) FROM test;}}
> shows 1.
> That is inconsistent.
