HDFS Federation and ViewFS support for multiple clusters

[#1]

Customer is running two clusters: PROD and DR. Both clusters have data and processing.

Each cluster is running a single NameNode (HA) with a single namespace for that cluster. Customer is looking for HDFS Federation and ViewFS support to be able to view files and directories in both clusters using a single interface.

I don't believe we support this scenario? Are there any other tools that provide "Windows Explorer" type interface to be able to navigate HDFS files and directories across multiple clusters?

@dbaev

You are right on the support part.

Re: HDFS explorer..check out this

@dbaev are you still having problems with this? Can you provide your own solution or accept best answer?

We are looking at HSFS federation and ViewFS official support in a major HDP release after HDP 2.6. We might also support NFSv3 working with ViewFS and if you have NFS clients, you should be able to browse the tree structure.
