> select_distinct_with_deletions_test failing in mixed version cluster
> --------------------------------------------------------------------

> Key: CASSANDRA-10762
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10762
> Project: Cassandra
> Issue Type: Sub-task
> Components: CQL
> Reporter: Philip Thompson
> Assignee: Sylvain Lebresne
> Fix For: 3.0.x
>
>
> 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)]
