Description

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

  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 
  

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
