Joan Fontanals created SPARK-29877: -------------------------------------- Summary: static PageRank allow checkPoint from previous computations Key: SPARK-29877 URL: https://issues.apache.org/jira/browse/SPARK-29877 Project: Spark Issue Type: Wish Components: GraphX Affects Versions: 2.3.0 Reporter: Joan Fontanals Fix For: 2.3.0
It would be really helpful to have the possibility, when computing staticPageRank to use a previous computation as a checkpoint to continue the iterations. I have done a small code proposal, but there is a problem because at the end of the iterations a normalization step is performed. Therefore, if we use this normalized graph as a checkpoint for a new set of iterations, the algorithm will not restart in a coherent way. I created a branch in my fork: [https://github.com/JoanFM/spark/tree/pageRank_checkPoint] I hope you can consider this feature, and if you do that you can implement yourself or propose me a way to handle this identified problem Thank you very much, Best regards, Joan -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
