> The dtests {{upgrade_tests.cql_tests.TestCQLNodes3RF3.select_distinct_with_deletions_test}}
and {{upgrade_tests.cql_tests.TestCQLNodes2RF1.select_distinct_with_deletions_test}} are failing.

> While in a mixed node state, they do {{'SELECT DISTINCT k FROM t1'}} on this table
> {{CREATE TABLE t1 (k int PRIMARY KEY, c int, v int)}}
> More rows than expected are returned. Here is the sample output of one of those queries.
As you can see, there are duplicate values of k returned in a DISTINCT k query. Seems like
a bug when communicating between the 2.2 and 3.0 node.
> {code}
> [Row(k=5), Row(k=1), Row(k=1), Row(k=8), Row(k=8), Row(k=2), Row(k=2), Row(k=4), Row(k=4),
Row(k=7), Row(k=7), Row(k=6), Row(k=6), Row(k=9), Row(k=9), Row(k=3), Row(k=3)]
