Hi everyone,
I'm trying to wrap my head around Cassandra great ability to expand…
I have set up my first Cassandra node a while ago… it was working great, and
data wasn't so important back then.
Since I had a great experience with Cassandra I decided to migrate step by step
my MySQL data to Cassandra.
Now data start to be important, so I would like to create another node, and add
it.
Since I had some issue with my DataCenter, I wanted to have a copy (of sensible
data only) on another DataCenter.
Quite frankly I'm still a newbie on Cassandra and need your guys help.
First things first…
Already up and Running Cassandra (Called A):
- Do I need to change anything to the cassandra.yaml to make sure that
another node can connect ? if yes, should I restart the node (because I would
have to warn users about downtime) ?
- Since this node should be a seed, the seed list is already set to
localhost, is that good enough ?
The new node I want to add (Called B):
- I know that before starting this node, I should modify the seed list
in cassandra.yaml… Is that the only thing I need to do ?
It is my first time doing this, so please be gentle ;-)
Thank you all,
Morgan.
