             Summary: HDFS NameNode Federation support
                 Key: ATLAS-2444
                 URL: https://issues.apache.org/jira/browse/ATLAS-2444
             Project: Atlas
          Issue Type: Bug
            Reporter: Apoorv Naik

With Hadoop 3, HDFS is introducing namespace/nameServiceId for data 

A cluster with hadoop 3 deployment can have multiple name nodes under a single 
name space and multiple namespace/nameserviceIds as well.

This metadata can be captured for other interested application/parties, eg. 
Ranger can use this to enforce policies per Namespace.



 # HDFS model to include a new attribute called nameServiceId, default will be 
 # hdfs path's qualified name will include the cluster info as well
 # All Hooks dealing with HDFS path will resolve the host:port to the 
respective nameServiceId
