Next Generation of Hadoop MapReduce by Owen O'Malley.
Federated HDFS by Sanjay Radia
Scalability of the NameNode has been a key struggle..
Federated HDFS allows multiple independent namespaces (and NameNodes) to share the physical storage within a cluster. This is enabled by the introduction of the notion of Block pools which is analogous to LUNs in a SAN storage system.
This approach offers a number of advantages besides scalability: it can isolate namespaces of different applications improving the overall availability of the cluster. The Block pool abstraction allows other services (such as HBase) to use the block storage with perhaps a different namespace structure.
Applications prefer to continue to use a singe namespace. Namespaces can be mounted to create such a unified view. A client-slide mount table provides
