[~iamaleksey] Thanks for reply but it's strange because before 2.1.6 we were receiving reports with few thousands of tombstones and after there are none.

> CASSANDRA-6042 introduced warning on too many tombstones scanned, then CASSANDRA-6117 introduced a hard TombstoneOverwhelmingException condition.
> However, at least {{SliceQuerFilter.collectReducedColumn()}} seems to have the logic wrong. Cells that are covered by a range tombstone or a partition high level deletion, still count towards {{ColumnCounter}}'s {{ignored}} register.
> Thus it's possible to have an otherwise healthy (though large) dropped partition read cause an exception that shouldn't be there.
> The only things that should count towards the exception are cell tombstones and range tombstones (CASSANDRA-8527), but never ever live cells shadowed by any kind of tombstone.
