Jason Brown commented on CASSANDRA-6124:
----------------------------------------
It is starting to look like LOCAL_ONE is useful. We have some internal users
that we startled to realize that once we opened up a second datacenter, that
their 99%ile was not as as consistent as before. I do have an alternate
solution to that in my back pocket ... but +1 to building in a CL.LOCAL_ONE
> 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)
> I've tested this patch and seems to work with our 1.2.5 deployment.
> Kindly review.
