Overview 2.1.1 Why a Workflow Dispatching System A complete data analysis system is usually composed of a large number of task units: shell scripts, java programs, mapreduce programs, hive scripts, etc. There is a time-dependent contextual dependency between task units In order to organize such a complex execution plan well, a workflow scheduling system is needed to schedule execution; for example, we might have a requirement that a business system produce 20G raw data a day and we process it every day, Processing steps are as follows: ...

Software is dominating the world. The core of the software is the algorithm. Algorithm tens of thousands of, and which algorithms belong to the "Crown Pearl"? Marcos Otero gave his opinion. What is an algorithm? In layman's terms, an algorithm is a well-defined computational process that can be used as input and produce values or a set of values as output. So the algorithm is a series of computational steps that convert input to output. -thomas H. Cormen,chales E.
