“Ozone is designed to scale to tens of billions of files and blocks and, in the future, even more.
Small files or huge number of datanodes are no longer a limitation”
So now Hadoop has gone futher Biggerrrrr. with this. it stores the information of named node in “Blocks” and can save trillions of data and unlimited data nodes.
with the of Kubernetes it can be feasible to use the system for efficient for distribution of the system.
