What is the function of hdfs in Hadoop?

HDFS (Hadoop Distributed File System) is a distributed file system within Hadoop that is primarily used for storing and managing large-scale data sets. Designed to store and process vast amounts of data across numerous servers, HDFS ensures high reliability, fault tolerance, and data access throughput.

HDFS splits data into multiple blocks and distributes them across multiple servers in a cluster to ensure high reliability and availability. Users can access, store, and process data in HDFS through various nodes in the Hadoop cluster.

Overall, the role of HDFS includes:

1. Storing massive datasets: HDFS can store data at the petabyte level and ensure reliable storage and management through a distributed approach.
2. Ensure high reliability and fault tolerance: HDFS guarantees the safety and reliability of data through data redundancy and replication mechanisms.
3. Supporting high throughput data access: HDFS enables parallel processing and reading/writing of large-scale data, facilitating high-performance data access.
4. Integrating with the Hadoop ecosystem: HDFS seamlessly integrates with other components in Hadoop, such as MapReduce and Spark, enabling large-scale data processing and analysis.
