Apache Spark is an open-source distributed general-purpose cluster-computing framework.Spark provides an interface for programming entire clusters with implicit data parallelism and fault tolerance.Originally developed at the University of California, Berkeley's AMPLab, the Spark codebase was later donated to the Apache Software Foundation, which has maintained it since Now that both Hadoop and Spark have been installed and you've started your clusters, you're ready to run a Spark job. Let's submit a word count example. First, copy and paste the following text into a file on your master machine that you can name alice.txt. Alice sits drowsily by a riverbank, bored by the book her older sister reads to her. Out of nowhere, a White Rabbit runs past her. Spark programs iteratively run about 100 times faster than Hadoop in-memory, and 10 times faster on disk [3]. Spark's in-memory processing is responsible for Spark's speed. Hadoop MapReduce, instead, writes data to a disk that is read on the next iteration. Since data is reloaded from the disk after every iteration, it is significantly slower than Spark [7]

Was ist Hadoop? - BigData Inside

Hadoop and Spark are not opposed to one another. In fact, they are complementary in ways that are essential for dealing with IOT's big data and fast analytics requirements. Specifically, Hadoop is a distributed data infrastructure (for clustering the data), while Spark is a data processing package (for cluster computing). Clustering the data - Apache Hadoop distributes massive data. Hadoop, Spark and other tools define how the data are to be used at run-time. This approach is called Schema-On-Read and allows maximum flexibility as to how data are used. The ETL step has now become a flexible part of the analytics application. In other words, applications are not limited to a predefined database schema and can allow the Data Scientist to determine how the raw data are to be.
