Spark pyspark与Spark提交 [英] Spark pyspark vs spark-submit
问题描述
有关spark-submit的文档中的内容如下:
The documentation on spark-submit says the following:
Spark的bin目录中的spark-submit脚本用于启动 集群上的应用程序.
The spark-submit script in Spark’s bin directory is used to launch applications on a cluster.
关于pyspark,它表示以下内容:
Regarding the pyspark it says the following:
您还可以使用bin/pyspark启动交互式Python Shell.
You can also use bin/pyspark to launch an interactive Python shell.
这个问题听起来很愚蠢,但是当我通过pyspark
运行命令时,它们也在集群"上运行,对吗?它们不只在主节点上运行,对吧?
This question may sound stupid, but when i am running the commands though pyspark
they also run on the "cluster", right? They do not run on the master node only, right?
推荐答案
这两者之间没有实际区别.如果未配置,则两者都将在本地模式下执行代码.如果配置了master(通过--master
命令行参数或spark.master
配置),则将使用相应的群集执行程序.
There is no practical difference between these two. If not configured otherwise both will execute code in a local mode. If master is configured (either by --master
command line parameter or spark.master
configuration) corresponding cluster will be used to execute the program.
