What i tried to do is writing complex data type to parquet file
Here is the schema of sink table. The problematic data type is
ARRAY<MAP<STRING,STRING>>
{code:java}
CREATE TEMPORARY TABLE local_table (
`user_id` STRING, `order_id` STRING, `amount` INT, `restaurant_id` STRING,
`experiment` ARRAY<MAP<STRING,STRING>>, `dt` STRING
) PARTITIONED BY (`dt`) WITH (
'connector'='filesystem',
'path'='file:///tmp/test_hadoop_write',
'format'='parquet',
'auto-compaction'='true',
'sink.partition-commit.policy.kind'='success-file'
) {code}
PS. It is used to work in Flink version 1.15.1
