Jonathan Ellis reassigned CASSANDRA-2406:
-----------------------------------------
Assignee: Pavel Yaskevich (was: Jonathan Ellis)
Pavel, can you take a stab at figuring out why the ranges overlap? They are
not supposed to.
(I am using https://github.com/pcmanus/ccm for testing, it saves a lot of time.)
> Secondary index and index expression problems
> ---------------------------------------------
>
> Key: CASSANDRA-2406
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2406
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.4
> Environment: CentOS 5.5 (64bit), JDK 1.6.0_23
> Reporter: Muga Nishizawa
> Assignee: Pavel Yaskevich
> Fix For: 0.7.5
>
> Attachments: CASSANDRA-2406-debug.patch, create_table.cli,
> node-1.system.log, secondary_index_checkv2.py, secondary_index_insertv2.py
>
>
> When I iteratively get data with secondary index and index clause, result of
> data acquired by consistency level "one" is different from the one by
> consistency level "quorum". The one by consistecy level "one" is correct
> result. But the one by consistecy level "quorum" is incorrect and is dropped
> by Cassandra.
> You can reproduce the bug by executing attached programs.
> - 1. Start Cassandra cluster. It consists of 3 cassandra nodes and
> distributes data by ByteOrderedPartitioner. Initial tokens of those nodes
> are ["31", "32", "33"].
> - 2. Create keyspace and column family, according to "create_table.cli",
> - 3. Execute "secondary_index_insertv2.py", inserting a few hundred columns
> to cluster
> - 4. Execute "secondary_index_checkv2.py" and get data with secondary index
> and index clause iteratively. "secondary_index_insertv2.py" and
> "secondary_index_checkv2.py" require pycassa.
> You will be able to execute 4th "secondary_index_checkv2.py" script with
> following option so that
> you get data with consistency level "one".
> % python "secondary_index_checkv2.py" -one
> On the other hand, to acquire data with consistency level "quorum", you will
> need to use following option.
> % python "secondary_index_checkv2.py" -quorum
> You can check that result of data acquired by consistency level "one" is
> different from one by consistency level "quorum".
