Difference Between Hadoop And Spark
It’s a powerful and general-purpose engine designed for massive-scale data processing. Spark is an execution engine that is able to run fast calculations on huge data sets. In this article, we will examine what makes Hadoop and spark distinct in terms of speed Storage, Speed, and Resource Management.

What is Hadoop?
Hadoop comprises two key components: HDFS as well as MapReduce. HDFS is a reliable, scalable, and efficient storage system for massive data sets. MapReduce is a model of programming that aids with big data processing.
Spark can run programs that are up 100 times more quickly over Hadoop MapReduce when running in memory, and 10x faster when it runs on disk. The reason for this is that the comparison is drawn by running iterative machine learning algorithms on each. Therefore, the actual performance could depend on the specific use. But, Spark is definitely the engine to be used when working on Machine Learning models. Thanks to the ML-Lib library that it has, it’s the perfect software that is ideal for Data Scientists.
However, Hadoop isn’t going to disappear with time since both have different uses or we don’t have the option of choosing any one of them over the others. It is mostly dependent on the use scenario and application.
It is equipped with a sophisticated DAG execution engine that can support Acyclic data flow as well as execution in memory.

For massive data sets, Spark uses existing distributed file systems, such as Hadoop HDFS, cloud storage alternatives like AWS S3, or even Big Data Databases such as Cassandra. Spark is also able to access data from local file systems however this isn’t the best option because it requires that data be accessible to every cluster node.
MapReduce comprises three primary phases. i.e. map-reduce and shuffle.
MapReduce is a programming model that was initially created by Google to allow the computation of massive data sets. Spark also employs MapReduce concepts. Spark’s objective is not to replace the MapReduce model, but rather in order to substitute Hadoop’s version by a more efficient and faster one.
One of the main factors that contribute to its speed is that it handles the computation of data within memory.
What’s the story with Interactive data mining?
For interactive data mining, you require a wide array of functions that let you perform an array of different operations on the data set and Spark offers various built-in functions that can be used for this purpose.
When using the traditional MapReduce You have to integrate your algorithm into reducers and mappers programs, which can be an obstacle. However, Spark offers a variety of built-in operations that can be used to accomplish the majority of the transform tasks.
Additionally, when performing the data mining process, you will have massive data sets that have lots of features. Spark assists us in increasing the speed of computation and delivering results within a short time.
