what is HDFS


HDFS is a file system to store the data in reliable manner. It consists of two types of nodes called NameNode and DataNode to store metadata and actual data.

HDFS is a block-structured file system. Just like Linux file systems, HDFS splits a file into fixed-size blocks, also known as partitions or splits. The default block size is 128 MB.
