I am trying to deploy a 4 node cluster i.e. Edge Node, Master Node and 2 Slave Nodes on azure using cloudbreak. I created security group including all hadoop services ports. While trying to create cluster using all services ports security group i am getting "port already in use by some services on azure" on some of hadoop ports. The ports on which i am seeing error is 8080,19888, 6188, 10015, 10000, 2181? any reason why i am getting such errors?
