Apache Spark is a dynamic execution engine that can take relatively simple Scala code and create complex and optimized execution plans. In this talk, we will describe how user code translates into Spark drivers, executors, stages, tasks, transformations, and shuffles. We will also discuss various sources of information on how Spark applications use hardware resources, and show how application developers can use this information to write more efficient code. We will show how Pepperdata’s products can clearly identify such usages and tie them to specific lines of code. We will show how Spark application owners can quickly identify the root causes of such common problems as job slowdowns, inadequate memory configuration, and Java garbage collection issues.
