   Apache Spark is a lot to digest; running it on YARN even more so. This article is an introductory reference to understanding Apache Spark on YARN. Since our data platform at Logistimoruns on this infrastructure, it is imperative you (my fellow engineer) have an understanding about it before you can contribute to it. This article assumes basic famil...

   YARN is a generic resource-management framework for distributed workloads; in other words, a cluster-level operating system. Although part of the Hadoop ecosystem, YARN can support a lot of varied compute-frameworks (such as Tez, and Spark) in addition to MapReduce. The central theme of YARN is the division of resource-management functionalities in...

   With our vocabulary and concepts set, let us shift focus to the knobs & dials we have to tune to get Spark running on YARN. We will be addressing only a few important configurations (both Spark and YARN), and the relations between them. We will first focus on some YARN configurations, and understand their implications, independent of Spark. 1. yarn...

   Spark can run with any persistence layer. For spark to run it needs resources. In standalone mode you start workers and spark master and persistence layer can be any - HDFS, FileSystem, cassandra etc. In YARN mode you are asking YARN-Hadoop cluster to manage the resource allocation and book keeping.

   What is the difference between a spark job and a YARN application?

   • A Spark job can consist of more than just a single map and reduce. On the other hand, a YARN application is the unit of scheduling and resource-allocation. There is a one-to-one mapping between these two terms in case of a Spark workload on YARN; i.e, a Spark application submitted to YARN translates into a YARN application.

   What is the difference between Spark and yarn?

   • A Spark application can be used for a single batch job, an interactive session with multiple jobs, or a long-lived server continually satisfying requests. A Spark job can consist of more than just a single map and reduce. On the other hand, a YARN application is the unit of scheduling and resource-allocation.

   What is the difference between yarn and spark standalone mode?

   • The Spark standalone mode requires each application to run an executor on every node in the cluster; whereas with YARN, you choose the number of executors to use agains Spark Standalone # executor/cores control, that shows how you can specify number of consumed resources at Standalone mode.

   How do I deploy a spark application on yarn?

   • There are two deploy modes that can be used to launch Spark applications on YARN. In cluster mode, the Spark driver runs inside an application master process which is managed by YARN on the cluster, and the client can go away after initiating the application.

   What is spark yarn mode?

   • Spark has a "pluggable persistent store". Spark can run with any persistence layer. For spark to run it needs resources. In standalone mode you start workers and spark master and persistence layer can be any - HDFS, FileSystem, cassandra etc. In YARN mode you are asking YARN-Hadoop cluster to manage the resource allocation and book keeping.

   Can spark run on yarn?

   • Spark can run on Yarn, the same way Hadoop Map Reduce can run on Yarn. It just happens that Hadoop Map Reduce is a feature that ships with Yarn, when Spark is not. If you mean comparing Map Reduce and Spark, I suggest reading this other answer. Apache Spark can be run on YARN, MESOS or StandAlone Mode.

   Mar 27, 2024 · Let me give a small brief on those two, Your application code is the set of instructions that instructs the driver to do a Spark Job and lets the driver decide how to achieve it with the help of executors. Instructions to the driver are called Transformations and action will trigger the execution.
