Subject [jira] [Created] (SPARK-25149) ParallelPersonalizedPageRank raises an error if vertexIDs are > MaxInt
Date Fri, 17 Aug 2018 17:59:00 GMT
Bago Amirbekian created SPARK-25149:
---------------------------------------

             Summary: ParallelPersonalizedPageRank raises an error if vertexIDs are > MaxInt
                 Key: SPARK-25149
                 URL: https://issues.apache.org/jira/browse/SPARK-25149
             Project: Spark
          Issue Type: Bug
          Components: GraphX
    Affects Versions: 2.3.1
            Reporter: Bago Amirbekian
             Fix For: 2.4.0


Looking at the implementation I think we don't actually need this check. The current implementation
indexes the sparse vectors used and returned by the method are index by the _position_ of
the vertexId in `sources` not by the vertex ID itself. We should remove this check and add
a test to confirm the implementation works with large vertex IDs.
