> ORC record reader unnecessarily parses stats twice
> {code}
> if (orcTail == null) {
> Reader orcReader = OrcFile.createReader(file.getPath(),
> OrcFile.readerOptions(context.conf)
> .filesystem(fs)
> .maxLength(AcidUtils.getLogicalLength(fs, file)));
> orcTail = new OrcTail(orcReader.getFileTail(),

> stripes = orcTail.getStripes();
> stripeStats = orcTail.getStripeStatistics();
> {code}
> We go from Reader -> OrcTail -> StripeStatistics.
> stripeStats is read out of the orcTail and is already read inside
> orcReader.getStripeStatistics().
