many connections within a cluster of product servers. It likewise indexes and keeps tracks of that data,
empowering big data analytics and processing far more proficiently than was probably earlier. Besides,
Spark is a data processing application which works on those circulated data collection. It doesn’t do
distributed storage.
2. Hadoop can be utilised without Apache Spark:
Hadoop contains not only a storage element, known as the Hadoop Distributed File System but also a
processing module named MapReduce, so you don’t want Spark for getting your processing done. Vice

works in steps, Spark works on the whole data set in one fell leap. Spark can be as much as ten times
