GaoLun commented on FLINK-3879:
-------------------------------
Scatter-gather model divides original iteration into two parts. For
performance, 3879 is better. Maybe it's good to keep both with different path.
One for performance, another for being consistent with other algorithm
implementations used same iteration model. :)

> Key: FLINK-3879
> URL: https://issues.apache.org/jira/browse/FLINK-3879
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan

> Fix For: 1.1.0

> Hyperlink-Induced Topic Search (HITS, also "hubs and authorities") is
> presented in [0] and described in [1].
> "[HITS] is a very popular and effective algorithm to rank documents based on
> the link information among a set of documents. The algorithm presumes that a
> good hub is a document that points to many others, and a good authority is a
> document that many documents point to."

> This implementation differs from FLINK-2044 by providing for convergence,
> outputting both hub and authority scores, and completing in half the number
> of iterations.
