Cassandra understands racks based on the configured snitch and the rack
assigned to each node (for example in cassandra-rackdc.properties if using
GossipingPropertyFileSnitch). If you have racks configured, to perform a
"rack-aware" repair you would simply need to run repair on only one rack.
Note
What command exactly do you think gives you a rack-aware repair?

I am getting ready to start what I understand as a rack aware repair. This is
to run the repair on each node within the rack resulting in a repair of the
entire cluster. My question comes due to a highly out of balance set of racks
and I want to know if Cassandra 2.1.12 is smart enough to identi
As far as I know, the main thing about using NetworkTopologyStrategy
and different racks is replica placement throughout your cluster. That
strategy favours different racks when it comes to choosing where a
row's replica will be placed. So, if you have different numbers of
nodes in each rack, you w
Hi Rob,
Thanks for sharing the link. I have gone through it and few other documents as
well. Still I am confused. It seems, if we use vnodes and
NetworkTopologyStrategy, we should use a single rack configuration in
Cassandra. Or, it can create hotspots in the ring. Not sure if my understanding

Hi,
I am new to Cassandra and trying to setup a Cassandra 2.0 cluster using 4
nodes, 2 each in 2 different racks. All are in same data centre. This is what I
see in the documentation:
To use racks correctly:
Use the same number of nodes in each rack. Use one rack and place the nodes in
