Phil Zampino updated KNOX-1167:
-------------------------------
Description:
In HDP 3, there will be support for multiple NameNode clusters (HDFS
Federation), qualified by disitinct namespaces, in a single Hadoop cluster.
Knox needs to provide the ability to distinguish these NN clusters in its
topologies for proxying WEBHDFS; the most practical means is a service
parameter.
The behavior for following needs to be defined:
* Multiple NN clusters, and a descriptor which does not specify such a
namespace. Which NN cluster will be chosen at discovery-time?
