HDFS Router-Based Federation
---------------------
HDFS Router-Based Federation adds a RPC routing layer that provides a federated
view of multiple HDFS namespaces. This is similar to the existing
[ViewFs](./hadoop-project-dist/hadoop-hdfs/ViewFs.html)) and
[HDFS Federation](./hadoop-project-dist/hadoop-hdfs/Federation.html)
functionality, except the mount table is managed on the server-side by the
routing layer rather than on the client. This simplifies access to a federated
cluster for existing HDFS clients.
See [HDFS-10467](https://issues.apache.org/jira/browse/HADOOP-10467) and the
HDFS Router-based Federation
[documentation](./hadoop-project-dist/hadoop-hdfs/HDFSRouterFederation.md) for
more details.
