"A Standby read-only HDFS NameNode, with no RPC server, that services clients over a REST API, utilizes Java 8 Stream API, all for the purpose of performing large and complicated scans of the entire file system metadata for end users."

Run a demo locally and instantly! Just run the following command on a workspace directory:

git clone nna && cd ./nna && ./gradlew execute
