Andra Lungu created FLINK-2360:
----------------------------------
Summary: EOFException
Key: FLINK-2360
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:

With a similar configuration to the one in FLINK-2293.
Fails with:
