> For thread safe purpose,  a ReflectionStructObjectInspector instance would wait for 3 seconds to ensure the returning ObjectInspector is fully inited, 
> {code:java}
> synchronized (soi) {
>   while (!soi.isFullyInited(checkedTypes)) {
>     // ....  
>     soi.wait(3000);  
>   }
> } {code}
> It seems that we are missing to notify ThriftUnionObjectInspector when it has been inited.
