I noticed that mapr seems to create a bunch of nodes in zookeeper at the root level. We use zookeeper for a number of things and would love to keep it more orderly. Additionally, we would potentially like to run more than one mapr cluster against a single zookeeper cluster. Can we move everything to a separate subnode (e.g. /mapr/batch-cluster and /mapr/realtime-cluster)? Is it possible to run multiple clusters of mapr against a single zk cluster?
