Is it possible to spicify node IP for datanode?

Because datanode will have to have a huge storage. So, it would be good if I can specify which node in cluster to be used as a datanode.

_OR!_ It's OK if I can just specify nodes for NameNode, JournalNode and ZKFC and let the rests be datanode.

Hi @teamsoo , In current release, I think the answer is no. A possible solution is that define some tip information like "mesos.hdfs.journalnode.hostname" in mesos-site.xml, then Hdfs-mesos can launch task based on user's needs.

correct @tangzhankun, the answer is no currently. Thanks for bringing up this issue @teamsoo! Constraints in HDFS-Mesos may be quite useful
