------------------------------------
Summary: GraphX computes Pagerank with NaN (with some datasets)
Key: SPARK-10945
URL: https://issues.apache.org/jira/browse/SPARK-10945
Project: Spark
Issue Type: Bug
Components: GraphX
Affects Versions: 1.3.0
Environment: Linux
Reporter: Khaled Ammar
Hi,
I run GraphX in a medium size standalone Spark 1.3.0 installation. The pagerank
typically works fine, except with one dataset (Twitter:
http://law.di.unimi.it/webdata/twitter-2010). This is a public dataset that is
commonly used in research papers.
I found that many vertices have an NaN values. This is true, even if the
algorithm run for 1 iteration only.
Thanks,
-Khaled
