>             Project: Parquet
>          Issue Type: Bug
>          Components: parquet-mr
>    Affects Versions: 1.5.0, 1.6.0, 1.7.0, 1.8.0
>            Reporter: Cheng Lian

> The following two schemas probably shouldn't be allowed to be union-ed when strict schema-merging mode is on:
> {noformat}
> message t1 {
>   required fixed_len_byte_array(10) f;
> }
> message t2 {
>   required fixed_len_byte_array(5) f;
> }
> {noformat}
> But currently {{t1.union(t2, true)}} yields {{t1}}.
