>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6363
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>         Environment: Linux/x64 2.0.2 4-node cluster

> CREATE TABLE session (
>   id text,
>   usr text,
>   valid int,
>   PRIMARY KEY (id)
> );
> insert into session (id, usr) values ('abc', 'abc');
> update session using ttl 1 set valid = 1 where id = 'abc';
> (wait 1 sec)
> And 
> delete from session where id = 'DSYUCTCLSOEKVLAQWNWYLVQMEQGGXD' if usr ='demo';
> Yields:
>  [applied] | usr
> -----------+-----
>      False | abc
> Rather than applying the delete.
> Executing:
> update session set valid = null where id = 'abc';
> and again
> delete from session where id = 'DSYUCTCLSOEKVLAQWNWYLVQMEQGGXD' if usr ='demo';
> Positively deletes the row.
