Subject [jira] [Updated] (HDFS-10467) Router-based HDFS federation
Date Tue, 10 Oct 2017 01:34:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10467?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Íñigo Goiri updated HDFS-10467:
-------------------------------
    Release Note: 
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 and HDFS federation 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 and the HDFS Router-based Federation documentation for more details.

  was:
HDFS Router-Based Federation adds a routing layer to provide a federated view of multiple
namespaces.
Users can interact with this new Router as it was a regular Namenode to access the federated
view.
It uses a mount table to decide which folders are mounted in which namespace (similar to ViewFs).

See the HDFS Router-Based Federation documentation for more details on how to set it up.
