Subject [GraphFrame, Pyspark] Weighted Edge in PageRank
Date Thu, 01 Dec 2016 22:41:30 GMT
Hi guys,

I am trying to compute the pagerank for the locations in the following
dummy dataframe,

*src    des      shared_gas_stations*
 A       B               2
 A       C              10
 C       E               3
 D       E              12
 E       G               5
...

I have tried the function *graphframe.pageRank(resetProbability=0.01,
maxIter=20)* in GraphFrame but it seems like this function doesn't take
weighted edges. Maybe I am not using it correctly. How can I pass the
weighted edges to this function? Also I am not sure if this function works
for the undirected graph.


Thanks a lot!
