---------------------------------
Summary: Flink hangs before starting execution
Key: FLINK-2603
URL:
https://issues.apache.org/jira/browse/FLINK-2603 Project: Flink
Issue Type: Bug
Components: Distributed Runtime
Affects Versions: master, 0.9.1
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}
