How to access different directories in a Hadoop cluster

Question

I've configured my cluster with HDFS Federation. One NameNode manages the /data namespace and another NameNode manages the /reports namespace. How do I configure a client machine to access both the /data and the /reports directories on the cluster?

Answer 1

You need to configure the client to mount both namespaces by specifying the appropriate properties in the core-site.xml.
  
Keep a note that HDFS Federation improves the existing HDFS architecture through a clear separation of namespace and storage, enabling generic block storage layer. It enables support for multiple namespaces in the cluster to improve scalability and isolation. Federation also opens up the architecture, expanding the applicability of HDFS cluster to new implementations and use cases.

Hope this helps!
