Subject Re: Implicit Router Configurations

You can use the server/scripts/cloud-scripts/zkcli.sh script (or the cmd
one) in server/scripts/cloud-scripts. Note, in older versions this is in
example/scripts/cloud-scripts. 

I just used this command to get the file from zookeeper:

server/scripts/cloud-scripts/zkcli.sh -z localhost:9983 -cmd getfile
/clusterstate.json clusterstate.json

You can use -cmd putfile to push it back to Zookeeper. As Erick says,
have all nodes on your cluster down at the time. And as Erick says, this
is not something that people are recommended to be doing generally.
