--------------------------------
Summary: Default value type does not match the return type of
method input()
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
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()};
