Greg Lee created SPARK-28662:
--------------------------------
Summary: Create Hive Partitioned Table without specifying data
type for partition columns will success unexpectedly
Key: SPARK-28662
URL: https://issues.apache.org/jira/browse/SPARK-28662
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.0.0
Reporter: Greg Lee
Fix For: 3.0.0
*Case :*
Create Hive Partitioned Table without specifying data type for partition column
will success unexpectly.
{code:java}
// create a hive table partition by b, but the data type of b isn't specified.
CREATE TABLE tbl(a int) PARTITIONED BY (b) STORED AS parquet
{code}
*Root Cause:*
In https://issues.apache.org/jira/browse/SPARK-26435 , PARTITIONED BY clause
are extended to support Hive CTAS as following:
{code:java}
// Before
(PARTITIONED BY '(' partitionColumns=colTypeList ')’
//After
(PARTITIONED BY '(' partitionColumns=colTypeList ‘)’|
PARTITIONED BY partitionColumnNames=identifierList) |
{code}
Create Table Statement like above case will pass the syntax check, and
recognized as (PARTITIONED BY partitionColumnNames=identifierList) 。
We should check this case in visitCreateHiveTable and give a explicit error
message to user
