Hi, We have introduced a new configuration file deployment.cfg [1]. Python will load the relevant initial configurations from this file including server node names. Therefore nodes.txt file is removed.
When loading node names in the cluster initially had a problem of spawning instances in OpenStack in a random order. This issue was solved using python collections.OrderedDict [3] instead of using default dictionary (unordered). Cluster information is kept in a config.pp file [2].
