I have 2 dc cassandra 3.0.14 setup. I need to add 2 new nodes to each dc.
I started one node in dc1 and its already joining. 3TB of 50TB finished in 2 weeks. One year ttl time series data with twcs.
I know, its not best practise..
I want to start one node in dc2 and cassandra refused to start with mentioning already one node in joining state.
I find some workaround with jmx directives, but i'm not sure if I broke something on the way.
Is it wise to bootstrap in both dc at the same time?
