[jira] [Commented] (HAMA-359) Development of Shortest Path Finding Algorithm

    [ https://issues.apache.org/jira/browse/HAMA-359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13027739#comment-13027739 ] 

Thomas Jungblut commented on HAMA-359:
--------------------------------------

Little update what I did the last two hours:

- Rewritten the GSoCDijkstra class in terms of fitting into HBase:
-- Did some fancy polymorphism to be able to test locally and use hbase on a cluster
--- added few interfaces and their implementations
-- remove the vertex class and just deal with the htable IDs to fit into the table layout


TODO:

- partitioning stuff (quite urgent)
- concrete hbase implementation
- vertexSet must be put into an abstraction layer in case of outsourcing into htable
-- currently this is just a hashmap representation of the original htable of the adjacency list
- Finish Output: make a more sophisticated method like every path from source with its cost
- afterwards do a full profiling of cpu and memory
