[jira] [Created] (MADLIB-1100) PageRank default threshold value seems to be 1e-5

---------------------------------------

             Summary: PageRank default threshold value seems to be 1e-5
                 Key: MADLIB-1100
                 URL: https://issues.apache.org/jira/browse/MADLIB-1100
             Project: Apache MADlib
          Issue Type: Bug
          Components: Module: Graph
            Reporter: Nandish Jayaram
             Fix For: v1.12


The threshold parameter in MADlib's pagerank is supposed to be 1/(num_of_vertices * 100) as mentioned in the docs. But the default value seems to be 1e-5 instead. This causes PageRank to converge right after the first iteration for larger graphs (million nodes graph).
