Hi there, I've been using Apache Ignite 1.8 in standalone mode for a while and as I'm upgrading to 2.5.0 I'm trying to use YARN deployment (https://apacheignite.readme.io/docs/yarn-deployment).
I deployed Ignite and it is running fine on YARN using ZooKeeper discovery but when I increase the number of nodes (IGNITE_NODE_COUNT) seemingly they start in the same host as the first node started until the host is out of resources to start another one or when it reaches a total of 5 nodes started in sequence. As I didn't found any documentation about node distribution or number of nodes in parallel on one host I'm concluding this based on some experiments that I've made. I found a parameter (/-m/) used with /start/ command (https://apacheignite-tools.readme.io/v2.5/docs/start-command) in ignitevisor that apparently do the trick and reinforces what I concluded about reaching 5 nodes (it's the default value for /-m/). I'd like to know if there is any option to change this policy when starting the cluster or if the only option is starting manually through the visor. Thanks in advance! -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
