Flink 1.11 SQL作业中调用UDTF 出现“No match found for function signature ”异常

hi all
本人基于Flink 1.11 SNAPSHOT 在 Flink sql 作业中使用 UDTF, UDTF 的定义如下：

@FunctionHint(
input = {@DataTypeHint("STRING"), @DataTypeHint("STRING")},
output = @DataTypeHint("STRING")
)
public class Split extends TableFunction<String> {
public Split(){}
public void eval(String str, String ch) {
if (str == null || str.isEmpty()) {
return;
} else {
String[] ss = str.split(ch);
for (String s : ss) {
collect(s);
}
}
}
}

在flink sql中通过 create function splitByChar as '**.**.Split' 来创建这个function，在tableEnv 中调用executeSql(....) 来完成对这个 function的注册，在sql 后面的计算逻辑中通过以下方式来调用这个UDTF
create view view_source_1 as select `dateTime，`itime`, lng,lat,net,event_info, cast(split_index(T.s, '_', 0) as int) as time_page from view_source as a left join LATERAL TABLE (splitByChar('a,b,c',',')) as T(s) on true;

结果一直出现以下错误信息：

之前在flink 1.10 里面使用是正常的，问下各位大佬有没有在flink 1.11 遇到过这个错误，麻烦提供一下帮助。

Re: Flink 1.11 SQL作业中调用UDTF 出现“No match found for function signature ”异常

我感觉这应该是新版本的udf的bug，我在本地也可以复现。
已经建了一个issue[1] 来跟进。

In reply to this post by Benchao Li-2

这个问题解决了吗？现在1.11.2仍然有这个问题，或者有什么临时解决方案，
registerFunction已经不好使了，createTemporarySystemFunction 报错 No match found for
function signature

Re: Flink 1.11 SQL作业中调用UDTF 出现“No match found for function signature ”异常

这个问题已经解决了，在1.11.1版本应该就已经修复了。
可以贴下具体的代码和异常栈，看下是不是还有其他问题，还是使用方式的问题。
