> We are pulling in Name Node federation support in HDFS/HDP 3.0 urgently, however, all our customers requires Ambari support for NN Federation. This is a major pain point for many customers and is part of PayPal's get well plan as well will be required for the large Daimler's deal.
> Details
> ======
> What NN federation allows is to share the Data Nodes between a set of independent Name Nodes. Each NN has its own standby and has the meta-data pointing to the blocks in the data nodes, however, they might share the Data Nodes. This will let us scale to 250M files for each NN and add more NNs as we go beyond 250M files.
> Ambari support will be required to make sure we can manage and configure NN federation.
