>             Project: Cassandra
>          Issue Type: Bug
>          Components: CQL
>         Environment: Linux Debian Wheezie 7.8 / Oracle Java 1.7.0_67
> Ubuntu 14.04.3 LTS / Oracle Java 1.7.0_75
> Cassandra 2.0.12 2.1.5 2.1.8

> We use CQLSStableWriter to produce testing datasets.
> Here are the steps to reproduce this issue :
> 1) definition of a table with counter
> {code}
> CREATE TABLE my_counter (
>   my_id text,
>   my_counter counter,
>   PRIMARY KEY (my_id)
> )
> {code}
> 2) with CQLSSTableWriter initialize this table (about 2millions entries) with this insert
order (one insert / key only)
> {{UPDATE myks.my_counter SET my_counter = my_counter + ? WHERE my_id = ?}}
> 3) load the files written by CQLSSTableWriter with sstableloader in your cassandra cluster
(tested on a single node and a 3 nodes cluster)
> 4) start a process that updates the counters (we used 3millions entries distributed on
the key my_id)
> 5) after a while try to query a key in the my_counter table
> {{cqlsh:myks> select * from my_counter where my_id='0000001';}}
> Request did not complete within rpc_timeout.
