In Hadoop, ____ is a critical factor in designing a disaster recovery plan for high availability.
- Data Compression
- Data Encryption
- Data Replication
- Data Serialization
Data Replication is a critical factor in designing a disaster recovery plan for high availability in Hadoop. By replicating data across multiple nodes, Hadoop ensures that there are redundant copies of the data, reducing the risk of data loss in case of node failure. This redundancy enhances fault tolerance and supports disaster recovery efforts.
