Federation: namenode storage directory must be configurable specific to a
namenode
----------------------------------------------------------------------------------
Key: HDFS-1914
URL: https://issues.apache.org/jira/browse/HDFS-1914
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.23.0
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: 0.23.0
Federation allows common configuration where namenode specific configuration
are in the same configuration suffixed by nameservice ID. When namenodes use an
external storage directory (NFS), in order to make namenodes use different
directories on the external server, the storage directory configuration must
also allow specific configuration, using nameservice ID.
