Jeremy Hanna commented on CASSANDRA-6124:
-----------------------------------------
Interesting - most people usually use an IP within the datacenter they want and
use CL.LOCAL_QUORUM afaik. That or CL.ONE and rely on the nodes don't get
overloaded so it wouldn't cross DC boundaries because of the dynamic snitch
modifier.
This keeps it in the same DC regardless of the CL from what it looks like,
which is convenient.
> Ability to specify a DC to consume from when using ColumnFamilyInputFormat
> externally

> Our production environment looks like this:
> - 6 cassandra nodes (online DC)
> - 3 cassandra nodes (offline DC)
> - Hadoop cluster.
> we are interested in connecting to the offline DC from hadoop (not colocated
> with cassandra offline dc)

> Kindly review.
