Greg Hogan resolved FLINK-2603.
-------------------------------
Resolution: Not A Problem
I believe this is due to a configured limit in the size of Akka messages as
discussed on the mailing list. The solution for my use case is to use a
`SplittableIterator` rather than generating data locally and transmitting over
the network.
> Flink hangs before starting execution
> -------------------------------------
>
> Key: FLINK-2603
> URL: https://issues.apache.org/jira/browse/FLINK-2603
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 0.9.1, 0.10.0
> Reporter: Greg Hogan
>
> The following simple application created from Flink's Java quickstart will
> hang before execution if the data size is to large. I have tested this on
> both 0.9.1 and master (7364ce18) and the threshold occurs with
> $ ./bin/flink run /path/to/blocks/target/blocks-1.0-SNAPSHOT.jar 19
> running in a few seconds while
> $ ./bin/flink run /path/to/blocks/target/blocks-1.0-SNAPSHOT.jar 20
> seemingly hangs forever.
> I first put this together two months ago so if it is a bug it is not a new
> bug.
> {code}
> package blocks;
> import java.util.ArrayList;
> import java.util.List;
> import org.apache.flink.api.java.ExecutionEnvironment;
> import org.apache.flink.api.java.io.DiscardingOutputFormat;
> public class Job {
> public static void main(String[] args) throws Exception {
> // set up the execution environment
> final ExecutionEnvironment env =
> ExecutionEnvironment.getExecutionEnvironment();
> List<Long> data = new ArrayList<>();
> int count = 1 << Integer.valueOf(args[0]);
>
> for (int i = 0 ; i < count ; i++) {
> data.add(0L);
> }
> env.fromCollection(data).output(new DiscardingOutputFormat());
> System.out.println("Ready to execute ...");
>
> // execute program
> env.execute("Flink Java API Skeleton");
> }
> }
> {code}
