> *TEST CASE*
> * Install three node cluster with C* 0.7.9 with node1 as the seed
> * Run the 0.7.9 stress tool against node2,node3: ./stress -d node2,node3 -o insert
> * Run `nodetool -h node1 drain`
> * Upgrade binaries and edit cassandra.yaml for node1.  
> * Startup C* 1.0 on node
> * Run the 0.7.9 stress tool against node2,node3: ./stress -d node2,node3 -o insert
> *ISSUE*
> * Run the 0.7.9 stress tool to read data: ./stress -d node2 -o read
> {code}
> cathy3:~/apache-cassandra-0.7.9-src/contrib/stress/bin# ./stress -d cathy3 -o read
> total,interval_op_rate,interval_key_rate,avg_latency,elapsed_time
> Operation [17] retried 10 times - error reading key 0521977 
> Operation [9] retried 10 times - error reading key 0595365 
> Operation [15] retried 10 times - error reading key 0513247 
> {code}
> *Additional notes*
> * There are no errors in the log files
> * After upgrading the full ring, and running READ from both the old and new versions of stress tool, the error still exists
> * Once all nodes are upgraded, if I run INSERT followed by READ, the new reads are fine
