Following are some approaches that came to my mind and few questions I need to get clarified. As I understand, all 3 major components (Resource Manager, File Manager and the Workflow Manager) *use several other files (ex: xml files located at policy/*)* which are used for additional configuration (ex: for mime type repository). However, all those file locations are found through properties in the *.properties* file at runtime. When implementing distributed configuration management, I have two options. 1. *Assuming that all such files are the same for all nodes*, ask users to copy the same OODT distribution files to all nodes when setting up the cluster. This assumes only the *.properties* file will have node specific configuration. 2. Otherwise, If I am allowed to write to */policy/** directory, I can download those files from zookeeper and make them available for each node at runtime. The problems I have at the moment are, 1. Whether my assumption in *suggestion 1 above* is correct? 2. Are there any node specific configurations in *.properties* files of any component? Can you kindly review my suggestions and help me clarify ambiguities I have? Your suggestions are also welcome. Thank you!
