> When trying to use the map complex data type as part of dynamic column mask,
> Hive throws a parsing error as it is expecting a primitive type (see trace
> pasted below). The use case is trying to apply masking to elements within a
> map type by applying a custom hive UDF (to apply the mask) using Ranger.
> Expect Hive to support complex data types for masking in addition to the
> primitive types. The expectation occurs when Hive need to evaluate the UDF or
> apply a standard mask (pass-through works as expected). You can recreate the
> problem by creating a simple table with a map data type column, then applying
> the masking to that column through a Ranger resource based policy and a
> custom function (you can use a standard Hive UDF str_to_map('F4','XXXX') to
> simulate returning a map).
> CREATE TABLE `mask_test`(
> `key` string,
> `value` map<string,string>)
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.mapred.TextInputFormat'
>
> INSERT INTO TABLE mask_test
> SELECT 'AAA' as key,
> map('F1','2022','F2','2222','F3','3333333') as value
> FROM (select 1 ) as temp;
