Apache Spark is developed in Scala programming language and runs on the JVM. In This article, we will explore Apache Spark installation in a Standalone mode. Hadoop YARN: In this mode, the drivers run inside the application’s master node and is handled by YARN on the Cluster.Apache Mesos: In this mode, the work nodes run on various machines, but the driver runs only in the master node.Standalone Cluster Mode: In this mode, it uses the Job-Scheduling framework in-built in Spark.Standalone Mode: Here all processes run within the same JVM process.It is a combination of multiple stack libraries such as SQL and Dataframes, GraphX, MLlib, and Spark Streaming. Hadoop - Schedulers and Types of SchedulersĪpache Spark is a lightning-fast unified analytics engine used for cluster computing for large data sets like BigData and Hadoop with the aim to run programs parallel across multiple nodes.
