One months of subway reading time, read the "Spark for Python Developers" ebook, not moving pen and ink do not read, readily in Evernote do a translation, for many years do not learn English, entertain themselves. Weekend finishing, found that more do a little more basic written, so began this series of Subway translation. In this chapter, we will build a separate virtual environment for development, complementing the environment with the Pydata

For more than 90% of people who want to learn spark, how to build a spark cluster is one of the greatest difficulties. To solve all the difficulties in building a spark cluster, jia Lin divides the spark cluster construction into four steps, starting from scratch, without any pre-knowledge, covering every detail of the

Spark example: Sorting by array and spark example Array sorting is a common operation. The lower performance limit of a comparison-based sorting algorithm is O (nlog (n), but in a distributed environment, we can improve the performance. Here we show the implementation of array sorting in Spark, analyze the performance, and try to find the cause of performance imp
