Description

Using the following json file:

{ "a" : null, "b" : [ ["B1", "B2"] ] }

The following CTAS query fails because parquet doesn't support a list directly nested inside another. We should improve the error message to better explain this:

0: jdbc:drill:zk=local> create table t2241 as select * from `2241.json`;
Query failed: Unsupported type LIST
