2. Think about Spark Broadcast variable as a Python simple data type like list, So the problem is how to pass a variable to the UDF functions. Here is an example: Suppose we have ages list d and a data frame with columns name and age. So we want to check if the age of each person is in ages list.spark的调试问题. spark运行过程中的数据总是以RDD的方式存储，使用Logger等日志模块时，对RDD内数据无法识别，应先使用行为操作转化为scala数据结构然后输出。. scala Map 排序. 对于scala Map数据的排序，使用 scala.collection.immutable.ListMap 和 sortWiht (sortBy),具体用法如下 ...

Thread Pools. One of the ways that you can achieve parallelism in Spark without using Spark data frames is by using the multiprocessing library. The library provides a thread abstraction that you can use to create concurrent threads of execution. However, by default all of your code will run on the driver node.

So when you say it should execute self.decode_module() inside the nodes, PySpark tries to pickle the whole (self) object (that contains a reference to the spark context). To fix that, you just need to remove the SparkContext reference from the telco_cn class and use a different approach like using the SparkContext before calling the class ...2.

Here is an example: Suppose we have ages list d and a data frame with columns name and age. So we want to check if the age of each person is in ages list.3. Spark RDD Broadcast variable example. Below is a very simple example of how to use broadcast variables on RDD. This example defines commonly used data (country and states) in a Map variable and distributes the variable using SparkContext.broadcast () and then use these variables on RDD map () transformation. 4.
