Hello everyone, A customer is sensitive to sharing information among users and would like to dedicate part of a cluster just for HBase, storage and computing power. That means constraining Hdfs files to be housed on the HBase dedicated nodes, so that no user on the cluster, apart from the ones with permissions to use HBase will be able to write on those nodes.
