Dear All,

We have a 13 Node cluster setup in e.g. US-EAST-1a.

Now we require to add few more components i.e. cassandra/zookeeper/rmp

I went through operation guide but not able to find how to add new cassandra/zookeeper. How i can add new zookeeper/cassandra to existing cluster ?

Also if i use second availability zone i.e. US-EAST-1b then will i face any issues ? as new components i.e. zookeeper/cassandra/rmp will be in US-EAST-1b and they have to communicate with US-EAST-1a components.

so last year i took our 18 server installations (2 datacenters each) and expanded them to 27 servers (3 datacenters each)

I got some input from Apigee about this, and labbed everything out so as to avoid issues.

Our expansion included adding a new RMP stack in each environment, and cass & zk services.

In a nutshell the process looked like this:

back everything up.
make sure you have it backed up and can restore.
prep your new servers (you will need the IP addresses)
update existing cass and zk configs and topology (i have a script i used to handle this that is a bit of a mess)
restart those services
install new cs/zk services
change replication factor of Cass
repair all instances
validate
we did more here - but you only asked about cass and zk

There is an architect inside Apigee that fed me the seed info i needed to make this expansion work. Baring that if you can figure out how to get someone at Apigee to put you in touch w/ me I can share my notes.
