Replication causes data redundancy then why is is pursued in HDFS?..

Answer / Rakesh Kumar Gupta

Replication is pursued in HDFS to provide high availability and fault tolerance. Although replication leads to data redundancy, it ensures that the system can continue functioning even if one or more DataNodes fail. In addition, Hadoop's distributed nature allows for efficient processing of large datasets by leveraging multiple nodes.
