Problem

LinkRank Scoring mechanism in Apache Nutch 1.x currently works in pure map-reduce pattern. Moreover, Apache Nutch is not optimized for graph-processing operations. Due to this nature of Nutch, scoring calculation could have been more efficient if done by a graph-processing library that runs with Bulk Synchronous Parallel model. Moreover, Apache Nutch 2.x which has slightly different architecture than 1.x, lacks LinkRank scoring. So rather than porting it to the new architecture, a cross-version solution would be nice to have.
