             Summary: Data is not filtered out when using WHERE clause on cluster column
                 Key: CASSANDRA-7636
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7636
             Project: Cassandra
          Issue Type: Bug
         Environment: Cassandra 2.1.0-rc4
            Reporter: Krzysztof Zarzycki


I encountered a weird, invalid situation with my cluster. I have a table on which I'm running some SELECTs with WHERE clause filtering on cluster columns, but the rows are not getting filtered out. 
Look: 
 select * from page_view where website_id = xxx and user_id = 'some_user' and page_id =0; -- tried also page_id<0 >0

 website_id | user_id   | page_id  | ...
------------+-----------+----------+----
        xxx | some_user | 21044533 | ...
...more rows here, none with page_id=0

The filtering on other (partition) columns runs fine. Only the clustering column is somewhat malfunctioning. 

Important is, how I got to this table:
1. I collected data with Cassandra version 2.0.8
2. I snapshotted the data, and removed the main copy from cluster's data.
3. I upgraded cluster to version 2.1.0-rc4
4. I've recreated the schema of tables in new version.
5. I ran sstableloader on the data to load data to new upgraded cluster.
6. I spotted the problem with filtering.
7. I've tried to run nodetool repair, nodetool upgradesstables -a , neither helped. 

I'm not deleting the invalid data. I'm eager to help investigating the issue if someone instructs me how to do it.
