[jira] [Created] (FLINK-29152) Describe statement resutls is different from the Hive
Shengkai Fang created FLINK-29152:
-------------------------------------
Summary: Describe statement resutls is different from the Hive
Key: FLINK-29152
URL: https://issues.apache.org/jira/browse/FLINK-29152
Project: Flink
Issue Type: Bug
Components: Connectors / Hive
Affects Versions: 1.16.0
Reporter: Shengkai Fang
In hive, the results schema is
{code:java}
+-----------+------------+----------+
| col_name | data_type | comment |
+-----------+------------+----------+
| a | int | |
| b | string | |
+-----------+------------+----------+
{code}
but our implementation is
{code:java}
0: jdbc:hive2://localhost:10000/default> describe sink;
+-------+-------+-------+-------+---------+------------+
| name | type | null | key | extras | watermark |
+-------+-------+-------+-------+---------+------------+
| a | INT | true | NULL | NULL | NULL |
+-------+-------+-------+-------+---------+------------+
{code}
BTW, it's better we can support {{DESCRIBE FORMATTED}} like hive does.
{code:java}
