Hi Andreas, I have recommend my customer to build a hdfs pool resources outside mesos cluster in general concerns. But in development or stage environment, use mesos to manage your hdfs culster is ideal purpose. when mesos community give more production case, then we can upgrade the develop cluster to production cluster easily.
