We want to create a data lake with HDFS Federated Namenode & multiple namespaces of clients. 1) Is this possible using HDFS federated namenode? 2) Is HDFS Federation officially supported by hortonworks if licensing are in-place? Kindly do the needful & Help.@Kuldeep Kulkarni Rahul Pathak Best Regards,

@Jacqualin jasmin, you name any directory on your datanodes as the data directory. Make sure of the permissions and the value of the dfs.datanode.data.dir parameter in HDFS configurations. e.g. /dev/vdb 1.5T 70M 1.4T 1% /volumes/disk1 dfs.datanode.data.dir=/volumes/disk1/hadoop/data/ after that you will find the VERSION file into the data directory once your HDFS detects the data directory.

@ripunjay godhani, you can change the mentioned parameter size in byte and it will then allow you to change block size for new data. You are asked to restart all affected service components after this to take it into the impact.
