> |part|Inner Join with Table Function (UDTF)|
> |origin|TableFunction<String> split = new MySplitUDTF();|
> |change to|TableFunction<Tuple3<String,String,String>> split = new MySplitUDTF();|
> I have run the following the codes successfully

> ②[MySplitUDTF.java|https://paste.ubuntu.com/p/Q6fDHxw4Td/]
> Reason:
> In this part, 
> it says:
> joinLateral(call("split", $("c")).as("s", "t", "v"))
> it means:
> the udtf has 1 input "c",
> and 3 outputs "s", "t", "v"
> So:
> these outputs should have 3 types.
> such as TableFunction<Tuple3<String,String,String>>
> instead of only 
> -TableFunction<String> split-
