How to solve “Neither Jetty ALPN nor OpenSSL via netty-tcnative were properly configured”?

Question

I'm trying to create a Dataflow job in order to insert rows in BigTable, but while I'm testing the Dataflow job locally I get the following error:

Exception in thread "main" com.google.cloud.dataflow.sdk.Pipeline$PipelineExecutionException: java.lang.IllegalStateException: Neither Jetty ALPN nor OpenSSL via netty-tcnative were properly configured.
at com.google.cloud.dataflow.sdk.Pipeline.run(Pipeline.java:186)

Bellow you can find my Main code:

    CloudBigtableOptions options =
            PipelineOptionsFactory.fromArgs(args).withValidation().create().as(CloudBigtableOptions.class);

    options.setProject("xxxxxxxxx");
    options.setBigtableProjectId("xxxxxxxxx");
    options.setBigtableInstanceId("xxxxxxxxx");
    options.setBigtableTableId("xxxxxxxxx");
    options.setZone("europe-west1-b");
    options.setRunner(DirectPipelineRunner.class);

    CloudBigtableTableConfiguration config =
            CloudBigtableTableConfiguration.fromCBTOptions(options);

    Pipeline p = Pipeline.create(options);
    CloudBigtableIO.initializeForWrite(p);

    FixedWindows window = FixedWindows.of(Duration.standardMinutes(1));

    p
            .apply(Create.of("Hello"))
            .apply(Window.into(window))
            .apply(ParDo.of(MUTATION_TRANSFORM))
            .apply(CloudBigtableIO.writeToTable(config));

    p.run();

Another try has been with the following code:

    CloudBigtableTableConfiguration config =
            new CloudBigtableTableConfiguration.Builder()
                    .withProjectId("xxxxxxxxx")
                    .withInstanceId("xxxxxxxxx")
                    .withTableId("xxxxxxxxx")
                    .build();

    Pipeline p = Pipeline.create(options);
    CloudBigtableIO.initializeForWrite(p);

    FixedWindows window = FixedWindows.of(Duration.standardMinutes(1));

    p
            .apply(Create.of("Hello"))
            .apply(Window.into(window))
            .apply(ParDo.of(MUTATION_TRANSFORM))
            .apply(CloudBigtableIO.writeToTable(config));

    p.run();

But I got the same error.

Am I doing something wrong?

Answer 1

我们刚刚发布了与Netty tcnative-boringssl-static配对的0.9.1客户端 ，如连接器示例所示，我们使用Fork19，而pardo hello示例不再需要使用os.detected 。

Answer 2

Problem was that the extension os-maven-plugin , to initialize the "os.detected" properties, didn't initialize the property correctly.

I've done a test setting the property corrrectly and the test has been executed without problems.
