The premise of this article is that scala, sbt, and spark have been correctly installed. Briefly describe the steps to mount the program to the cluster for running: 1. Build the sbt standard project structure: Where :~ /Build. the sbt file is used to configure the basic information of the project (project name, organization name, project version, scala version us

Qingming Holiday toss for two days, summed up two ways to use the IDE for the Spark program, record: The first method is simpler, both of which are compiled with SBT. Note: There is no need to install the Scala program locally, otherwise there is a version compatibility issue when compiling the program. First, based on the NON-SBT way Create a Scala idea project We use the NON-
