> Key: CASSANDRA-14899
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14899
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Major
> Fix For: 2.2.14
>
>
> CASSANDRA-11196 accidentally broke reading from tables with mixed clustering
> column order in the opposite direction.
> {{ReversedPrimaryKeyRestrictions::boundsAsComposites}} method attempts to
> reverse the list returned from
> {{PrimaryKeyRestrictionSet::boundsAsComposites}} and fails, as Guava’s
> {{Lists::transform}} method returns a {{List}} that doesn’t support {{set()}}.
> Reproduction:
> {code}
> CREATE TABLE test.test (
> a int,
> b int,
> c int,
> PRIMARY KEY (a, b, c)
> ) WITH CLUSTERING ORDER BY (b ASC, c DESC);
> SELECT * FROM test.test WHERE a = 0 AND (b, c) > (0, 0) ORDER BY b DESC, c
> ASC;
> > ServerError: java.lang.UnsupportedOperationException
> {code}
> {code}
