>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6327
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>         Environment: Cassandra 2.0.2, x86-64 Ubuntu 13.10
>            Reporter: Duncan Sands
>         Attachments: current_prices.tar

> This query returns no result:
> cqlsh:tick_data> select syd from current_prices where shard = 1 and syd in (1, 556129);
> (0 rows)
> However this query does return a result, showing that the previous query was wrong to
return no result:
> cqlsh:tick_data> select syd from current_prices where shard = 1 and syd in (556129);
>  syd
> --------
>  556129
> (1 rows)
> This can be reproduced as follows:
> (a) Create a keyspace tick_data:
> create keyspace tick_data WITH replication = {'class': 'SimpleStrategy', 'replication_factor':
1};
> (b) Create a table current_prices:
> CREATE TABLE current_prices (
>   shard int,
>   syd int,
>   ask decimal,
>   bid decimal,
>   currency ascii,
>   when timeuuid,
>   PRIMARY KEY (shard, syd)
> );
> (c) Stop Cassandra and untar the attached tar file in /var/lib/cassandra/data/tick_data/.
 It populates the current_prices table.
> (d) Restart Cassandra and perform the above selects.
