> Before we can get the ColumnStatistics from RowIndex we need to determine whether it exists or not.
> entry.getStatistics(); does not return null at any time, and will return a default object when  it is not set.
>  
> {code:java}
>       OrcProto.ColumnStatistics colStats = entry.getStatistics();
>       if (colStats == null) {
>         buf.append("no stats at ");
>       }
> {code}
