> In case the Iceberg Parquet table lands up having an empty batch, in that 
> case while fetching the row number, used for filtering leads to NPE.
> The row number to block mapping is only done if the parquetSplit isn't null, 
> so in that case, here:
> {code:java}
> if (parquetInputSplit != null) {
>   initialize(parquetInputSplit, conf);
> } {code}
> row numbers aren't initialised, so we should skip fetching the row numbers 
> later
