----------------------------------
Summary: Index Out of Bounds Exception
Key: FLINK-2412
URL: https://issues.apache.org/jira/browse/FLINK-2412
Project: Flink
Issue Type: Bug
Components: Local Runtime
Affects Versions: 0.10
Reporter: Andra Lungu
When running a code as simple as:
ExecutionEnvironment env =
ExecutionEnvironment.getExecutionEnvironment();
DataSet<Edge<String, NullValue>> edges = getEdgesDataSet(env);
Graph<String, NullValue, NullValue> graph =
Graph.fromDataSet(edges, env);
DataSet<Tuple2<String, Long>> degrees = graph.getDegrees();
degrees.writeAsCsv(outputPath, "\n", " ");
env.execute();
on the Freindster data set: https://snap.stanford.edu/data/com-Friendster.html;
on 30 Wally nodes
I get the following exception:
java.lang.Exception: The data preparation for task 'CoGroup (CoGroup at
inDegrees(Graph.java:701))' , caused an error: Error obtaining the sorted

Code works fine for the twitter data set, for instance, which is bigger in
size, but contains less vertices.
