             Summary: [1.11.0] jobmanager complains `taskmanager.memory.process.size` missing
                 Key: FLINK-18350
                 URL: https://issues.apache.org/jira/browse/FLINK-18350
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Configuration
    Affects Versions: 1.11.0
            Reporter: Steven Zhen Wu


 

Saw this failure in jobmanager startup. I know the exception said that `taskmanager.memory.process.size` missing. We set it at taskmanager side in `flink-conf.yaml`. But I am wondering why is this required by jobmanager for session cluster mode. When taskmanager registering with jobmanager, it reports the resources (like CPU, memory etc.).

We extend from WorkerResourceSpecFactory similar to KubernetesWorkerResourceSpecFactory.
{code:java}
public class TitusWorkerResourceSpecFactory extends WorkerResourceSpecFactory {

  public static final TitusWorkerResourceSpecFactory INSTANCE =
      new TitusWorkerResourceSpecFactory();

  @Override
  public WorkerResourceSpec createDefaultWorkerResourceSpec(Configuration configuration) {
    return workerResourceSpecFromConfigAndCpu(configuration, getDefaultCpus(configuration));
  }

  @VisibleForTesting
  static CPUResource getDefaultCpus(Configuration configuration) {
    double fallback = Double.valueOf(System.getenv("TITUS_NUM_CPU"));
    return TaskExecutorProcessUtils.getCpuCoresWithFallback(configuration, fallback);
  }
}
