> 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
