Description

For thread safe purpose,  a ReflectionStructObjectInspector instance would wait for 3 seconds to ensure the returning ObjectInspector is fully inited, 

synchronized (soi) {
  while (!soi.isFullyInited(checkedTypes)) {
    // ....  
    soi.wait(3000);  
  }
} 

It seems that we are missing to notify ThriftUnionObjectInspector when it has been inited.
