where the driver is located should be configured as much as possible based on the actual situation. At the same time, it is also crucial that the driver and spark cluster should be in the same network environment, and should be the executor of the worker for the driver to be continuously assigned to tasks, and the driver data should be accepted at the same time; Q4: I am currently solving stackoverflow

　　the core of the Spark data store is the elastic distributed Data Set (RDD). The Rdd can be abstracted as a large array, but the array is distributed over the cluster. logically each partition of the RDD is called aPartition.During the execution of Spark, the RDD undergoes a transfomation operator and is finally trigg

Original address The idea of real-time business intelligence is no longer a novelty (a page on this concept appeared in Wikipedia in 2006). However, although people have been discussing such schemes for many years, I have found that many companies have not actually planned out a clear development idea or even realized the great benefits. Why is that? One big reason is that real-time business intelligence and analytics tools are still very limited on the market today. Traditional

About SparkSpark is the common parallel of the open source class Hadoop MapReduce for UC Berkeley AMP Lab, Spark, with the benefits of Hadoop MapReduce But unlike MapReduce, the job intermediate output can be stored in memory, thus eliminating the need to read and write HDFs, so spark is better suited for the algorithm of map reduce, such as data mining and machi
