Re: Seed nodes and bootstrap (was: Re: Initializing a multiple node cluster (multiple datacenters))

That ticket was before I was really active contributing, but I tend to agree with your assessment: clearly there's pain point there, and we can do better than the status quo. The problem (as Jonathan notes) is that its a complicated subsystem, and the "obvious" fix probably isn't as obvious as it

It comes up from time to time. Rob Coli spent years arguing that this behavior was confusing ( https://issues.apache.org/jira/browse/CASSANDRA-5836 ) , especially in the "I'm replacing a failed seed" sense. It also comes up when you're adding the first few hosts to a new DC (where they're new,

Re: Initializing a multiple node cluster (multiple datacenters)

In my opinion and experience, this isn’t a real problem, since you define a list of seeds as the first few nodes you add to a cluster. When would you add a node to an existing cluster and mark itself as a seed? It’s neither practical or something you’d do by accident. > On Feb 23, 2018,

Re: Initializing a multiple node cluster (multiple datacenters)

Hi jonathan Thank you for the answer. Do you know where to look to understand why this works. As i understood all the node then will chose ramdoms tokens. How can i assure the correctness of the ring? So as you said. Under the condition that there.is no data in the cluster. I can initialize a

Re: Initializing a multiple node cluster (multiple datacenters)

If it's a new cluster, there's no need to disable auto_bootstrap. That setting prevents the first node in the second DC from being a replica for all the data in the first DC. If there's no data in the first DC, you can skip a couple steps and just leave it on. Leave it on, and enjoy your

Hello I would like to clarify this, In order to initialize a cassandra multi dc cluster, without data. If I follow the documentation datastax https://docs.datastax.com/en/cassandra/2.1/cassandra/initialize/initializeMultipleDS.html It says - auto_bootstrap: false (Add this setting
