hello, I meet a problem just like this: My flink version is 1.12.0,and I change the version to 1.12.3, the problem still exist.
I create two tables which have data type map, I want to union two tables to one, but when i run on sql-client, I met such a problem:(number_feature is a map data)
but when I run this sql,it has correct result:"(SELECT query FROM map_string_string1) UNION (SELECT query FROM map_string_string2)"
The reason why it cannot support map union is a problem?
this is my create table statements:
CREATE TABLE `map_string_string1`(
`query` string,
`wid` string,
`index` int,
`page` string,
`hc_cid1` string,
`hc_cid2` string,
`hc_cid3` string,
`cid1` string,
`cid2` string,
`cid3` string,
`ts` bigint,
`number_feature` map<string,string>)
PARTITIONED BY (
`dt` string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
LINES TERMINATED BY '\n'
STORED AS INPUTFORMAT
'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
CREATE TABLE `map_string_string2`(
`query` string,
`wid` string,
`index` int,
`page` string,
`hc_cid1` string,
`hc_cid2` string,
`hc_cid3` string,
`cid1` string,
`cid2` string,
`cid3` string,
