--------------------------------------
Hi Tyler, I have updated the dtest according to your new specification. do you
think it is needed? https://github.com/riptano/cassandra-dtest/pull/1199
> Duplicated Key in IN clause with a small fetch size will run forever
> --------------------------------------------------------------------
>
> Key: CASSANDRA-12420
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12420
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Environment: cassandra 2.1.14, driver 2.1.7.1
> Reporter: ZhaoYang
> Assignee: Tyler Hobbs
> Labels: doc-impacting
> Fix For: 2.1.16
>
> Attachments: CASSANDRA-12420.patch

>
> This can be easily reproduced and fetch size is smaller than the correct
> number of rows.
> A table has 2 partition key, 1 clustering key, 1 column.
> > Select select = QueryBuilder.select().from("ks", "cf");
> > select.where().and(QueryBuilder.eq("a", 1));
> > select.where().and(QueryBuilder.in("b", Arrays.asList(1, 1, 1)));
> > select.setFetchSize(5);
> Now we put a distinct method in client side to eliminate the duplicated key,
> but it's better to fix inside Cassandra.
