Deployment Environments¶

Spark Deployment Environments (Run Modes):

• local/spark-local.md[local]
• spark-cluster.md[clustered] ** spark-standalone.md[Spark Standalone] ** Spark on Apache Mesos ** yarn/README.md[Spark on Hadoop YARN]

A Spark application is composed of the driver and executors that can run locally (on a single JVM) or using cluster resources (like CPU, RAM and disk that are managed by a cluster manager).

NOTE: You can specify where to run the driver using the spark-deploy-mode.md[deploy mode] (using --deploy-mode option of spark-submit or spark.submit.deployMode Spark property).

== [[master-urls]] Master URLs

Spark supports the following master URLs (see https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L2583-L2592[private object SparkMasterRegex]):

• local, local[N] and local[{asterisk}] for local/spark-local.md#masterURL[Spark local]
• local[N, maxRetries] for local/spark-local.md#masterURL[Spark local-with-retries]
• local-cluster[N, cores, memory] for simulating a Spark cluster of N executors (threads), cores CPUs and memory locally (aka Spark local-cluster)
• spark://host:port,host1:port1,... for connecting to spark-standalone.md[Spark Standalone cluster(s)]
• mesos:// for spark-mesos/spark-mesos.md[Spark on Mesos cluster]
• yarn for yarn/README.md[Spark on YARN]

You can specify the master URL of a Spark application as follows:

1. spark-submit.md[spark-submit's --master command-line option],

2. SparkConf.md#spark.master[spark.master Spark property],

3. When creating a SparkContext.md#getOrCreate[SparkContext (using setMaster method)],

4. When creating a spark-sql-sparksession-builder.md[SparkSession (using master method of the builder interface)].
