Summary: DESCRIBE FORMATTED for columns produces wrong output when
the column datatype is STRUCT
Key: HIVE-29474
URL: https://issues.apache.org/jira/browse/HIVE-29474
Project: Hive
Issue Type: Bug
Reporter: tanishqchugh
Assignee: tanishqchugh
When we have a table that contains STRUCT type columns, the output of DESCRIBE
FORMATTED on the STRUCT type column produces wrong output.
For Exm:
{code:java}
CREATE TABLE tbl_t (id int, point STRUCT<x:INT, y:INT>);
DESCRIBE FORMATTED tbl_t point;{code}
gives the following output:
{code:java}
+------------------------+----------------------------------------------------+
| column_property | value |
+------------------------+----------------------------------------------------+
| col_name | x |
| data_type | int |
| min | |
| max | |
| num_nulls | |
| distinct_count | |
| avg_col_len | |
| max_col_len | |
| num_trues | |
| num_falses | |
| bit_vector | |
| comment | from deserializer |
| COLUMN_STATS_ACCURATE |
{\"BASIC_STATS\":\"true\",\"COLUMN_STATS\":{\"id\":\"true\"}} |
+------------------------+----------------------------------------------------+
{code}
We can see that the col_name & data_type contain the wrong values.
