Example 1 with ClusterDescriptor

use of org.apache.flink.client.deployment.ClusterDescriptor in project flink by apache.

the class AbstractSessionClusterExecutor method execute.

@Override

        checkState(clusterID != null);
        final ClusterClientProvider<ClusterID> clusterClientProvider = clusterDescriptor.retrieve(clusterID);
        ClusterClient<ClusterID> clusterClient = clusterClientProvider.getClusterClient();
        return clusterClient.submitJob(jobGraph).thenApplyAsync(FunctionUtils.uncheckedFunction(jobId -> {
            ClientUtils.waitUntilJobInitializationFinished(() -> clusterClient.getJobStatus(jobId).get(), () -> clusterClient.requestJobResult(jobId).get(), userCodeClassloader);
            return jobId;
