@Deprecated
  public FunctionInfo registerUDF(String functionName,
      Class<? extends UDF> UDFClass, boolean isOperator, FunctionResource... resources) {
    return registerUDF(functionName, UDFClass, isOperator, functionName.toLowerCase(), resources);
  }
@deprecated From next release, replaced by {@link #registerUDF(String, Class, boolean)}
Deprecated because method unnecessarily accepts and passes FunctionResource vararg param
