AWS Athena 插入命名列在 pyspark 中不起作用

Question

I've created a little test table using pyspark

query="""
CREATE EXTERNAL TABLE IF NOT EXISTS test1
(
c1 INT,
c2 INT,
c3 INT
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
LOCATION 's3://mybucket/myfolder/'
"""
spark.sql(query)

And this works fine, producing the following output

spark.sql("select * from test1").show()

+---+---+---+
| c1| c2| c3|
+---+---+---+
|  1|  2|  3|
|  4|  5|  6|
+---+---+---+

My problem is trying to do an insert now. According to my reading of the Athena documentation I should be able to do the following but I'm getting an error message

query="""
insert into test1(c1,c2,c3) select c1,c2,c3 from test1
"""
spark.sql(query)


"\nmismatched input 'c1' expecting {'(', 'SELECT', 'FROM', 'VALUES', 'TABLE', 'INSERT', 'MAP', 'REDUCE'}(line 2, pos 21)\n\n== SQL ==\n\ninsert into test1(c1,c2,c3) select c1,c2,c3 from test1\n---------------------^^^\n"
Traceback (most recent call last):

However the following INSERT works as expected

query="""
insert into test1 select c1,c2,c3 from test1
"""

spark.sql(query)

If anyone can see what I'm doing wrong it would be appreciated

As per AWS documentation, you don't need to pass the column names alongwith the destination table. The correct query would be:

insert into test1 select c1,c2,c3 from test1
