How is spark fault tolerance?

Question Posted / pawan kumar


How is spark fault tolerance?..

Answer / Apurav Garg

Apache Spark achieves fault tolerance by storing multiple copies of the same data across different nodes in a cluster. When a task fails, it can be re-executed on another node that has a copy of the data. Additionally, Spark maintains lineage information, allowing it to recalculate dependencies if needed.
