Why spark is faster than hadoop?

Question Posted / sirisha


Why spark is faster than hadoop?..

Answer / Anupam Bharati

Spark tends to be faster than Hadoop for several reasons: 1) In-memory processing reduces the need for disk I/O, 2) RDDs (Resilient Distributed Datasets) have fault tolerance without requiring checkpointing, and 3) Spark's DAG Scheduler optimizes the data flow between tasks.
