What is HDFS in Hadoop?

Question

Can anyone explain the HDFS in Hadoop?

Answer 1

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.
