>             Project: Flink
>          Issue Type: Bug
>          Components: Table SQL / Legacy Planner
>    Affects Versions: 1.12.0, 1.11.3
>            Reporter: Danny Chen
>            Assignee: Danny Chen
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.12.1

> Some of the rel data types for legacy planner:
> - {{GenericRelDataType}}
> - {{ArrayRelDataType}}
> - {{MapRelDataType}}
> - {{MultisetRelDataType}}
> Does not implement the digest correctly, especially for {{GenericRelDataType}} , the
{{RelDataTypeFactory}} caches the type instances based on its digest, a wrong digest impl
would mess up the type instance creation, e.g. without this patch, all the {{GenericRelDataType}}
instances have same digest `ANY`.
