>                 URL: https://issues.apache.org/jira/browse/FLINK-2360
>             Project: Flink
>          Issue Type: Bug
>          Components: Local Runtime
>    Affects Versions: 0.10
>            Reporter: Andra Lungu
>            Priority: Critical
>
> The following code:
> https://github.com/andralungu/gelly-partitioning/blob/master/src/main/java/example/NodeSplittingConnectedComponents.java
> What the code does, on a very high level:
> 1). Discovers the skewed nodes in a graph and splits them into subnodes, recursively, in levels until we achieve a more uniform degree distribution.
> 2). Creates a delta iteration that takes the split data set as a solution set. On this, it runs the Connected Components Algorithm. At the end of each superstep, the partial results computed by the subvertices is gathered back into the initial vertex, updating the overall value in the split vertices.
> 3). Once the iteration converged, the graph is brought back to its initial state.
> Ran on the twitter follower graph: http://twitter.mpi-sws.org/data-icwsm2010.html
> With a similar configuration to the one in FLINK-2293.
