What is the current stable version of Hadoop?
HDFS is based on a leader/follower architecture.
Each cluster is typically composed of a single NameNode, an optional SecondaryNameNode (for data recovery in the event of failure), and an arbitrary number of DataNodes.What is the architecture of HDFS?
The NameNode and secondary NameNode manage the HDFS metadata.
The DataNodes host the underlying HDFS data.
The NameNode tracks which DataNodes contain the contents of a given file in HDFS.
HDFS divides files into blocks and stores each block on a DataNode.What is Apache Hadoop HDFS?
The Hadoop Distributed File System ( HDFS ) is a distributed file system designed to run on commodity hardware.
It has many similarities with existing distributed file systems.
