> Key: FLINK-20700
> URL: https://issues.apache.org/jira/browse/FLINK-20700
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.12.0
> Reporter: ZhangWei
> Priority: Trivial
>
> In org.apache.flink.table.annotation.FunctionHint, the return type of input() is an
> array of DataTypeHint, while the default value is @DataTypeHint() which is just an object.
> So the method defination should be as below, *{}*should be added.
> DataTypeHint[] input() default \{@DataTypeHint()};
