> Key: GIRAPH-153
> URL: https://issues.apache.org/jira/browse/GIRAPH-153
> Project: Giraph
> Issue Type: New Feature
> Components: bsp
> Affects Versions: 0.1.0
> Environment: Single host OSX 10.6.8 2.2Ghz Intel i7, 8GB
> Reporter: Brian Femiano
> Attachments: GIRAPH-153.1.patch, GIRAPH-153.2.patch, GIRAPH-153.patch
>
>
> Four abstract classes that wrap their respective delegate input/output
> formats for
> easy hooks into vertex input format subclasses. I've included some sample
> programs that show two very simple graph
> algorithms. I have a graph generator that builds out a very simple directed
> structure, starting with a few 'root' nodes.
> Root nodes are defined as nodes which are not listed as a child anywhere in
> the graph.
> Algorithm 1) AccumuloRootMarker.java --> Accumulo as read/write source.
> Every vertex starts thinking it's a root. At superstep 0, send a message down
> to each
> child as a non-root notification. After superstep 1, only root nodes will
> have never been messaged.
> Algorithm 2) TableRootMarker --> HBase as read/write source. Expands on A1 by
> bundling the notification logic followed by root node propagation. Once we've
> marked the appropriate nodes as roots, tell every child which roots it can be
> traced back to via one or more spanning trees. This will take N + 2
> supersteps where N is the maximum number of hops from any root to any leaf,
> plus 2 supersteps for the initial root flagging.
> I've included all relevant code plus DistributedCacheHelper.java for
> recursive cache file and archive searches. It is more hadoop centric than
> giraph, but these jobs use it so I figured why not commit here.
> These have been tested through local JobRunner, pseudo-distributed on the
> aforementioned hardware, and full distributed on EC2. More details in the
> comments.
