> When using hiveModule, the if function is treated as a normal function.
>  If I have a SQL like this: 
>   
> {code:java}
>  insert into Sink select  if(size(split(`test`, '-')) > 1, split(`test`, '-')[2], 'error') from Source   {code}
>  
>  It will throw arrayIndexOutOfBoundsException in Flink1.10,  becase size(split(`test`, '-')-) > 1 ， split(`test`, '')[2]， ‘error’   will be calculated first, and then if function will be  calculated
