SparkConf 允许你配置一些通用的属性(如master URL、应用程序名称等等)以及通过set()方法设置的任意键值对。例如,我们可以用如下方式创建一个拥有两个线程的应用程序。 val conf = new SparkConf() .setMaster("local[2]") .setAppName("CountingSheep") .set("spark.executor.memory", "1g")val sc = new ...
Spark properties(Spark属性)可以控制绝大多数应用程序参数,而且既可以通过SparkConf对象来设置,也可以通过Java系统属性来设置。 Environment variables(环境变量)可以指定一些各个机器相关的设置,如IP地址,其设置方法是写在每台机器上的conf/中。 Logging(日志)可以通过log4j.properties配置日志。 Spark属性 Spark属性可以控...
