Hadoop Distributed File System (HDFS) is a distributed file system optimized for storing large data sets. It uses a master/slave architecture, wherein a cluster of machines is managed by a master node and each slave node holds a portion of the data. This structure allows for the efficient storage and retrieval of large datasets. For example, an HDFS cluster could be used to store a phonebook with the numbers of everyone in the United States.
People with surnames starting with A may have their numbers saved on server 1, B on server 2, and so on. This structure allows for quick and efficient retrieval of data. HDFS also supports fault tolerance, ensuring that the data is still accessible even if one of the nodes goes offline. This makes HDFS an ideal choice for applications that require large datasets to be stored and managed reliably.
What differences are HDFS & HBase
