Summary Today, we're not talking about complex technical implementations in Spark, just a little bit of code-behind. It's well known that Spark uses scala to develop because scala has lots of syntactic sugar on it, so many times it's time to get back the code and follow it, and Spark is based on information exchanged by Akka, so how do you know each other? Is the recipient? new Throwable (). printStackTrace In the code to read, users often ask for help in the log, reading the log ...
