Sergey Shelukhin commented on HIVE-16548:
-----------------------------------------
I can repro this on the same data... looks like the determination of what to
read is incorrect, it tries to read from the wrong place because the range from
disk is missing.
E.g. we try to get CB (or CBs, due to ORC index related safety margin at the
end) at [30615403, 30781251) from the stream at [30572092, 30781251), but the
corresponding two chunks from disk and/or cache are [30517488, 30571555) and
[30745405, 30781251) - the start of the range, and probably the entire CB we
want, is missing from the data. This can lead to all kinds of errors. Need to
investigate why.
