What is the purpose of HDFS in the Hadoop ecosystem, and how does it interact with Java applications?
HDFS (Hadoop Distributed File System) stores large datasets across multiple machines, allowing Java applications to read and write data efficiently in a distributed environment.
Thatâ€™s correct. HDFS is designed for scalable, distributed storage and is a core component of the Hadoop ecosystem.
Can you explain the concept of data replication in HDFS and how it ensures fault tolerance?
