Datanode servlets need information about the namenode to service the request
----------------------------------------------------------------------------
Key: HDFS-1669
URL: https://issues.apache.org/jira/browse/HDFS-1669
Project: Hadoop HDFS
Issue Type: Sub-task
Components: data-node, name-node
Affects Versions: Federation Branch
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: Federation Branch
Prior to federation datanode had only one namenode. In servlets hosted on
datanode, a DFSClient was created to the only namenode to serve the request.
However with federation datanode has multiple namenodes. When a request is
redirected to a datanode, it does not know which namenode to use for servicing
the request.
This results in TestHftpFileSystem failure.
