[jira] Created: (HADOOP-4234) KFS: Allow KFS layer to interface
with multiple KFS namenodes
KFS: Allow KFS layer to interface with multiple KFS namenodes
-------------------------------------------------------------
Key: HADOOP-4234
URL: https://issues.apache.org/jira/browse/HADOOP-4234
Project: Hadoop Core
Issue Type: Bug
Reporter: Sriram Rao
Priority: Minor
Fix For: 0.19.0
The KFS "glue" layer code in Hadoop, currently, only allows an application to interface with a single KFS namenode. The KFS client side library has been modified to allow applications to interface with multiple KFS namenodes. This jira issue is for incorporating the change into the KFS code.

Providing a new patch since the previous one didn't work.
Re: no new test, this issue was found in a KFS deployment. To test this code path, a KFS+Hadoop deployment is required; that was done elsewhere.

@Tsz: In the patch that is submitted, in the Init() method, we don't need to check whether kfsImpl == null. The KFS client library code keeps track of all the servers to which the client is connected to; it build a new "handle" for each new server.
