------------------------------------
Summary: Improve Pagerank
Key: HAMA-591
URL: https://issues.apache.org/jira/browse/HAMA-591
Project: Hama
Issue Type: New Feature
Components: bsp core, graph
Affects Versions: 0.5.0
Reporter: Thomas Jungblut
We can now add more aggregators, for example to get how many dangling nodes
there are to spread probability mass correctly / get the number of global
vertices. Example in JENA [1].
Also we can extract a RandomWalkVertex that is abstracting the very distinct
behaviour of pagerank.
