Hi Vasia,
/InitVerticesMapper/ is called in the run method of APSP:
/
// @Override//
// public Graph<K, Tuple2<Integer[],String>, NullValue> run(Graph<K,
Tuple2<Integer[],String>, NullValue> input) {//
//
// VertexCentricConfiguration parameters = new
VertexCentricConfiguration();//
// parameters.setSolutionSetUnmanagedMemory(false);//
////
// return input.mapVertices(new InitVerticesMapper<K>(srcVertexId))//
// .runVertexCentricIteration(new
VertexDistanceUpdater<K, Tuple2<Integer[],String>, Integer>(srcVertexId),//
// new MinDistanceMessenger<K,
Tuple2<Integer[],String>, Integer, NullValue>(srcVertexId),//
// maxIterations, parameters);//
// }/
I'll send you the full code via a private e-mail.
Cheers,
Mihail

Hi Mihail,
could you share your code or at least the implementations of
getVerticesDataSet() and InitVerticesMapper so I can take a look?
Where is InitVerticesMapper called above?
Cheers,
Vasia.

Hi Robert,
I'm using the same input data, as well as the same parameters I
use in the IDE's run configuration.
I don't run the job on the cluster (yet), but locally, by starting
Flink with the start-local.sh script.
I will try to explain my code a bit. The /Integer[] /array is
initialized in the /getVerticesDataSet()/ method.
/ DataSet<Vertex<Integer, Tuple2<Integer[],String> >>
vertices = getVerticesDataSet(env);//
// ...//
// Graph<Integer, Tuple2<Integer[],String>, NullValue>
graph = Graph.fromDataSet(vertices, edges, env);//
// ...//
// Graph<Integer, Tuple2<Integer[],String>, NullValue>
intermediateGraph = //
// graph.run(new APSP<Integer>(srcVertexId,
maxIterations));/
In APSP I'm addressing it in the /InitVerticesMapper/, but is now
suddenly empty.
Best,
Mihail

Hi Mihail,
the NPE has been thrown from
/graphdistance.APSP$InitVerticesMapper.map(APSP.java:74)/. I
guess that is code written by you or a library you are using.
Maybe the data you are using on the cluster is different from
your local test data?
Best,
Robert

Hi,
I get an ArrayIndexOutOfBoundsException when I run my job
from a JAR in the CLI.
This doesn't occur in the IDE.
I've build the JAR using the "maven-shade-plugin" and the
pom.xml configuration Robert has provided here:
https://stackoverflow.com/questions/30102523/linkage-failure-when-running-apache-flink-jobs
I specify the entry point using the "-c" option.
The array the Exception refers to is actually initialized
when a vertices dataset is read from the file system.
Any ideas on what could cause this issue?
Best,
Mihail
