Data integrity refers to the consistency, accuracy, and trustworthiness of data. In HDFS, data integrity is ensured through various mechanisms like replication, checksums, and error correction. Each data block is checked for errors before being written to multiple datanodes, and any errors are corrected using techniques like checksum and replica comparison. These measures help in maintaining the integrity of data blocks stored in HDFS.
