HI, I have 11 compute nodes. I want to create a hadoop cluster with 1 master(namenode+jobtracker) with 20 worker (datanode+tasktracker). How to configure the Anti-affinty so I can run the master in one host, while others will be hosting two worker? I tried some configuration, but I can not achieve it.
