Description

1. create table schema_test2 (string1 string) stored as parquet;
2. insert into schema_test2 values ('test'); --> all queries work fine after this
3. alter table schema_test2 add columns (string2 string);
4. select * from schema_test2 --> works fine
5. select string2 from schema.test2 -> prints "NULL" unstoppedly
6. select distinct string2 from schema.test2 -> query hangs
