It would be a lot easier to answer you question if you showed the output from nodetool ring.

This would only make sense if you had 2 data centres, with at least 2 nodes in each. 
You probably just want {DC1:2}

This means there are not enough available nodes to perform the request at the Consistency
Level you code has requests. Probably due to the strategy_options set above.
