I am trying to find all paths from node A to node B with pathLength < 10 using GraphFrames. I can do it using the following code, but, was wondering if there is a better way to do this. val gra...

My aim is to find whether the max path length between two vertices is <= 4. I have a graph dataframe and a test file of the below format. I am trying to get the output column(OP) from bfs fun...

graphframes is a network analysis tool based on PySpark DataFrames. The following code is a modified version of the tutorial subgraphing example: from graphframes.examples import Graphs import gra...

I'm trying to use the graphframes package in pyspark in Jupyter Notebook (using Sagemaker and sparkmagic) on AWS EMR. I've tried adding a configuration option when creating the EMR cluster in the A...

I'm following this installation guide but have the following problem with using graphframes from pyspark import SparkContext sc =SparkContext() !pyspark --packages graphframes:graphframes:0.5.0-sp...

I am fighting it the whole day. I am able to install and to use a package (graphframes) with spark shell or a connected Jupiter notebook, but I would like to move it to the kubernetes based spark e...

I have created a GraphFrame in Spark and the graph currently looks as following: Basically, there will be lot of such subgraphs where each of these subgraphs will be disconnected to each other. ...

I am new to Python and stuck with building a hierarchy out of a relational dataset. It would be of immense help if someone has an idea on how to proceed with this. I have a relational data-set with...

I'm working with a largish (?) graph (60 million vertices and 9.5 billion edges) using Spark Graphframes. The underlying data is not large - the vertices take about 500mb on disk and the edges are ...

Suppose that I have created the following graph. My question is how can I visualize it? # Create a Vertex DataFrame with unique ID column "id" v = sqlContext.createDataFrame([ ("a", "Alice", 3...

I'm trying to find the connected components for friends in a city. My data is a list of edges with an attribute of city. City | SRC | DEST Houston Kyle -> Benny Houston Benny -> Charles Houston...

The graphFrames package of spark is great. I can find the shortest path from "a" to "d" with the command val results = g.shortestPaths.landmarks(Seq("a", "d")).run() but what how can I define a ...

I am trying to find the most efficient way to take the Map output from the GraphFrames function shortestPaths and flatten each vertex's distances map into individual rows in a new DataFrame. I've b...
