Hi,
Running the rebalancer script (by the way, you only need to run it once)
redistributes all of your data for you. That is, after you've run the
rebalancer, your data should be stored evenly among your 10 nodes.

hello everyone,
I have added 7 nodes to my 3 node cluster. I followed the following
steps
to
do this

1. added the node's ip to conf/slaves at master
2. ran bin/start-balance.sh at each node

As i loaded the data when the size of the cluster was three which is now
TEN. Can i do anything to redistribute the data among all the nodes?

Any ideas appreciated.

Thanks and Regards

Asif.
