----------------------------------------

> Mixed 2.0.14 - 2.1.4 Cluster Error Deserializing RangeSliceCommand
> ------------------------------------------------------------------
>
>                 Key: CASSANDRA-9136
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9136
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>         Environment: 3 Nodes GCE, N1-Standard-2, Ubuntu 12, 1 Node on 2.1.4, 
> 2 on 2.0.14
>            Reporter: Russell Alexander Spitzer
>             Fix For: 2.1.5
>
>
> This error occurs during a rolling upgrade between 2.0.14 and 2.1.4.
> h3. Repo
> With all the nodes on 2.0.14 make the following tables
> {code}
> CREATE KEYSPACE test WITH replication = {
>   'class': 'SimpleStrategy',
>   'replication_factor': '2'
> };
> USE test;
> CREATE TABLE compact (
>   k int,
>   c int,
>   d int,
>   PRIMARY KEY ((k), c)
> ) WITH COMPACT STORAGE;
> CREATE TABLE norm (
>   k int,
>   c int,
>   d int,
>   PRIMARY KEY ((k), c)
> ) ;
> {code}
> Then load some data into these tables. I used the python driver
> {code}
> from cassandra.cluster import Cluster
> s = Cluster().connect()
> for x in range (1000):
>     for y in range (1000):
>        s.execute_async("INSERT INTO test.compact (k,c,d) VALUES 
> (%d,%d,%d)"%(x,y,y))
>        s.execute_async("INSERT INTO test.norm (k,c,d) VALUES 
> (%d,%d,%d)"%(x,y,y))
> {code}
> Upgrade one node from 2.0.14 -> 2.1.4
> Run cqlsh on the upgraded node and certain queries will fail intermittently, 
> easiest to repo with CL = ALL
> {code}
> cqlsh> SELECT count(*) FROM test.norm where k = 22 ;
> ReadTimeout: code=1200 [Coordinator node timed out waiting for replica nodes' 
> responses] message="Operation timed out - received only 1 responses." 
> info={'received_responses': 1, 'required_responses': 2, 'consistency': 'ALL'}
