Piotr Findeisen commented on HIVE-22130:
----------------------------------------
Similarly there are problems when doing CTAS or INS from TEXTFILE to
SEQUENCEFILE or textual RCFILE.
> Incorrect data inserted when CTAS or INS from TEXTFILE to ORC with nested
> collection types

> {code}
> CREATE TABLE ttf (t_complex MAP<INT, ARRAY<STRUCT<s_string: STRING,
> s_double:DOUBLE>>>) STORED AS TEXTFILE;
> CREATE TABLE tor (t_complex MAP<INT, ARRAY<STRUCT<s_string: STRING,
> s_double:DOUBLE>>>) STORED AS ORC;
> INSERT INTO ttf VALUES (map(1, array(named_struct('s_string', 'test abc',
> 's_double', 1e-1), named_struct('s_string' , 'test xyz', 's_double', 2e-1))));
> INSERT INTO tor VALUES (map(1, array(named_struct('s_string', 'test abc',
> 's_double', 1e-1), named_struct('s_string' , 'test xyz', 's_double', 2e-1))));
> SELECT * FROM ttf;
> SELECT * FROM tor;
> {code}
> outputs
> {code}
> +----------------------------------------------------+
> | ttf.t_complex |

> | {1:[{"s_string":"test abc","s_double":0.1},{"s_string":"test

> +----------------------------------------------------+
> {code}
> But now when I do {{INSERT INTO .. SELECT}}:
> {code}
> INSERT INTO tor SELECT * FROM ttf;
> SELECT * FROM tor;
> {code}
> the data gets inserted incorrectly.
