> tbl1 is just used as a prop to create data, could be an existing directory
> for an external table.
> Due to weird behavior of LoadTableDesc (some ancient code for overriding old
> partition path), custom partition path is overwritten after the query and the
> data in it ceases being a part of the table (can be seen in desc formatted
> output with masking commented out in QTestUtil)
> This affects branch-1 too, so it's pretty old.
> {noformat}drop table tbl1;
> CREATE TABLE tbl1 (index int, value int ) PARTITIONED BY ( created_date
> string );
> insert into tbl1 partition(created_date='2018-02-01') VALUES (2, 2);
> CREATE external TABLE tbl2 (index int, value int ) PARTITIONED BY (
> created_date string );
> ALTER TABLE tbl2 ADD PARTITION(created_date='2018-02-01');
> ALTER TABLE tbl2 PARTITION(created_date='2018-02-01') SET LOCATION
> 'file:/Users/sergey/git/hivegit/itests/qtest/target/warehouse/tbl1/created_date=2018-02-01';
