-------------------------------------------
(patch is against 1.0 but probably needed by 0.8 too.)

> On Cassandra-1.0.5:
> 1. Create a node in C* with a fresh installation and create a keyspace on
> that node with one column family -
> CREATE KEYSPACE test
> WITH placement_strategy = 'SimpleStrategy'
> and strategy_options={replication_factor:1};
> use test;
> create column family cf1;
> 2. Insert values into cf1 -
> set cf1[ascii('k')][ascii('c')] = ascii('v');
> get cf1[ascii('k')];
> => (column=63, value=v, timestamp=1325689630397000)
> Returned 1 results.
> 3. update the strategy options from simple to networktopology with
> {Cassandra:1, Backup:1}
> 4. read from cf1 to make sure the options change doesn't affect anything -
> consistencylevel as LOCAL_QUORUM;
> get cf1[ascii('k')];
> => (column=63, value=v, timestamp=1325689630397000)
> Returned 1 results.
> 5. start a second node in the Backup datacenter
> 6. read from cf1 again (on the first node) -
> consistencylevel as LOCAL_QUORUM;
> get cf1[ascii('k')];
> Returned 0 results.
> After about 60 seconds, "get cf1[ascii('k')]" started to return results
> again.
> Also, when running at a CL of ONE on 1.0's head, we were able to see issues
> as well.
> But, if more than one node was added to the second datacenter, then
> replication_strategy is changed, it seems okay.
