There are truly non also many properties that nosotros must update inwards fellowship to fix the cluster. Note that inwards this detail example, nosotros volition last configuring ii nodes: 1 seed too 1 client.
Configuration
The Seed
"The seed node designation has no role other than bootstrapping the gossip procedure for novel nodes joining the cluster. Seed nodes are non a unmarried indicate of failure, nor produce they accept whatever other particular role inwards cluster operations beyond the bootstrapping of nodes."
Open too edit CASSANDRA_HOME/conf/cassandra.yaml
- rpc_address - laid to the IP address of the node
- seed_provider / parameters / seeds - laid to the ip address of the node
- listen_address - laid to the IP address of the node
Client Node
"All nodes inwards Cassandra are peers. H5N1 customer read or write asking tin become to whatever node inwards the cluster. When a customer connects to a node too issues a read or write request, that node serves equally the coordinator for that detail customer operation.
The labor of the coordinator is to human activity equally a proxy betwixt the customer application too the nodes (or replicas) that ain the information existence requested. The coordinator determines which nodes inwards the telephone should instruct the asking based on the cluster configured partitioner too replica placement strategy."
Open too edit CASSANDRA_HOME/conf/cassandra.yaml
- rpc_address - laid to the IP address of the node
- seed_provider / parameters/seeds - laid to the IP address of the seed node
- listen_address - laid to the IP address of the node
As yous tin encounter the alone departure is the value of the seeds.
Now commencement the Cassandra instance on the seed node, followed yesteryear the customer node. You should instruct the next log inwards the seed machine:

Can yous estimate which IP is the seed?
