             Summary: Fix Scala code examples for UDF type inference annotations
                 Key: FLINK-18672
                 URL: https://issues.apache.org/jira/browse/FLINK-18672
             Project: Flink
          Issue Type: Bug
          Components: Documentation, Table SQL / API
            Reporter: Fabian Hueske


The Scala code examples for the [UDF type inference annotations|https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/table/functions/udfs.html#type-inference] are not correct.

For example: the following {{FunctionHint}} annotation 

{code:scala}
@FunctionHint(
  input = Array(@DataTypeHint("INT"), @DataTypeHint("INT")),
  output = @DataTypeHint("INT")
)
{code}


needs to be changed to

{code:scala}
@FunctionHint(
  input = Array(new DataTypeHint("INT"), new DataTypeHint("INT")),
  output = new DataTypeHint("INT")
)
{code}
