Can we run spark without yarn?

As per Spark documentation, Spark can run without Hadoop. You may run it as a Standalone mode without any resource manager. But if you want to run in multi-node setup, you need a resource manager like YARN or Mesos and a distributed file system like HDFS,S3 etc.

Does Spark use YARN?

Spark on YARN

Spark uses two key components – a distributed file storage system, and a scheduler to manage workloads. Typically, Spark would be run with HDFS for storage, and with either YARN (Yet Another Resource Manager) or Mesos, two of the most common resource managers.

Can Spark run without a cluster?

Spark doesn’t need a Hadoop cluster to work. Spark can read and then process data from other file systems as well. … Spark does not have any storage layer, so it relies on one of the distributed storage systems for distributed computing like HDFS, Cassandra etc.

Why YARN is used in Spark?

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.
