Standalone application (self-contained applications)Now, based on a simple app, write a standalone application through the Spark API. Programs written in Scala need to be compiled and packaged using SBT, and Java programs are packaged using Maven, and Python programs are submitted directly via Spark-submit.PS: As if the spark2.0 supports a data set (DataSets) other than the RDD, the performance of Python p

Implementation of the standalone mode in javascriptAs a software development model, the single mode is widely used in many object-oriented languages. In javascript, the single mode is also widely used, however, javascript has its own unique object-oriented method.
