Problem 6. Basics for Spark Streaming and GraphX (Spark Streaming) Suppose we create a Spark Streaming Context "streamingContext" in Python Spark. streamingContext- StreamingContext(sc, 3) where "c" is the SparkContext instance. What does the second parameter "3" represent here? Answer: We want to stream the data from TCP source with IP Address "123.45.67.89" and port number "4321". Please provide the function for streaming data from that TCP source. The return variable is a (Spark GraphX) Suppose we have a graph in the following. 4 The left figure shows the graph, and the right column shows the edge list file. Suppose the full directory of the file is "/home/rob/data/ToyGrapho1.txt". "SC is the Spark Context. Please provide the command to load the graph edge list file in Scala 1: If we want to get the number of vertices, we should use the following command in Scala 1
