问题 In order to test and learn Spark functions, developers require Spark latest version. As the API's and methods earlier to version 2.0 are obsolete and no longer work in the newer version. This throws a bigger challenge and developers are forced to install Spark manually which wastes a considerable amount of development time. How do I use a later version of Spark on the Quickstart VM? 回答1: Every one should not waste setup time which I have wasted, so here is the solution. SPARK 2.2 Installation
