The Hadoop Distributed File System (HDFS), developed using distributed file system design, is the primary data storage system used by Hadoop applications

Features of HDFS:

  • It is mainly suitable for the distributed storage and data processing.
  • Hadoop has a command interface to interact with HDFS.
  • The built-in servers of the name node and data node allow the users to monitor the status of the cluster easily.
  • Streaming access to file system data.
  • HDFS provides file permissions and authentication.

If you are interested to learn Hadoop, I recommend this Hadoop Certification program by Intellipaat.

You can watch this video on HDFS to understand more:
