> Switching the field order within an array of structs causes the query to fail
> or return the wrong data for the fields, but switching the field order within
> just a struct works.
> How to reproduce:
> Case1 if the two fields have the same type, query will return wrong data for
> the fields
> drop table if exists schema_test;
> create table schema_test (msg array<struct<f1: string, f2: string>>) stored
> as parquet;
> insert into table schema_test select stack(2, array(named_struct('f1', 'abc',
> 'f2', 'abc2')), array(named_struct('f1', 'efg', 'f2', 'efg2'))) from one
> limit 2;
> select * from schema_test;
> --returns
> --[{"f1":"efg","f2":"efg2"}]
> --[{"f1":"abc","f2":"abc2"}]
> alter table schema_test change msg msg array<struct<f2: string, f1: string>>;
> select * from schema_test;
> --returns
> --[{"f2":"efg","f1":"efg2"}]
> --[{"f2":"abc","f1":"abc2"}]
> Case2: if the two fields have different type, the query will fail
> drop table if exists schema_test;
> create table schema_test (msg array<struct<f1: string, f2: int>>) stored as
> parquet;
> insert into table schema_test select stack(2, array(named_struct('f1', 'abc',
> 'f2', 1)), array(named_struct('f1', 'efg', 'f2', 2))) from one limit 2;
> select * from schema_test;
> --returns
> --[{"f1":"efg","f2":2}]
> --[{"f1":"abc","f2":1}]
> alter table schema_test change msg msg array<struct<f2: int, f1: string>>;
> select * from schema_test;
> Failed with exception
> java.io.IOException:org.apache.hadoop.hive.ql.metadata.HiveException:
> java.lang.ClassCastException: org.apache.hadoop.io.Text cannot be cast to
> org.apache.hadoop.io.IntWritable
