    Comment: was deleted

(was: I have been able to reproduce the ReadTimeoutException for the above given environment.
However I couldn't produce any WriteTimeoutException. The Application reads from one table
and updates to another table with Consistency QUORUM

>          Components: Core
>         Environment: centos 6.6 server, java version "1.8.0_45", cassandra 2.1.8, 3 machines,

> Test scenario is: kill -9 one node, wait 60 seconds, start it back, wait till it becomes
available, wait 120 seconds (during that time all 3 nodes are up), repeat with the next node.
Application reads from one table and updates counters in another table with consistency QUORUM.
When one node out of 3 is killed application logs this exception for several seconds:

write)
