Daniel Chia commented on CASSANDRA-10003:
-----------------------------------------
I think there's a combination of two things that causes the weirdness:
1) There's actually an issue in calculating timestamp, where we overflow the
(int) nowInSeconds in converting it into a timestamp. Due to bad (good?) luck,
up until really recently, this caused timestamp to overflow to a negative
number, which made non of the range tombstones actually shadow any of the data
in rows.
2) I think this test really meant to test the iterator without the
`removeShadowedData` flag set to true, but that's what the test does.
