What is HDFS federation?

Question

Can anyone tell me what is HDFS federation?

Answer 1

HDFS Federation is an enhancement to the HDFS architecture and separates the namespace and storage layer. This allows the scalability of independent namespace across multiple clusters or organizations. Here, all the data node will have their metadata in all the independent namenodes. This improves the scalability in case of new namenode addition.
