> If we create a table with type array<struct<>>, and later added a field in
> the struct, we got the following exception.
> The following SQL statements would recreate the error:
> {quote}
> CREATE TABLE pq_test (f1 array<struct<c1:int,c2:int>>) STORED AS PARQUET;
> INSERT INTO TABLE pq_test select array(named_struct("c1",1,"c2",2)) FROM tmp
> LIMIT 2;
> SELECT * from pq_test;
> ALTER TABLE pq_test REPLACE COLUMNS (f1
> array<struct<c1:int,c2:int,cccccc:int>>); //***** cccccc
> SELECT * from pq_test;
> {quote}
> Exception:
> {quote}
