ERROR : java.lang.IllegalArgumentException: Missing required pipeline options: region

[indrajitp]

I have Data in BigQuery and trying to migrate that to BigTable using BigQueryBigtableTransfer DF template.
running it like

mvn package exec:exec \
    -DBigQueryBigtableTransfer \
    -Dbigtable.projectID=google-cloud-project-id \
    -Dbigtable.instanceID=Big-table-instance-id-dev \
    -Dgs=gs://google-cloud-project-id-bigtable/bigtable_table/ \
    -Dbq.query='SELECT * FROM `google-cloud-project-id.SAMPLE.bigtable_test`' \
    -Dregion=us-west1	

With or without region still gives error of region parameter missing even if region paramater is no where mentioned in redme file.
getting below error -

Having the same issue, added this line and I was able to run the file

$ tail -14  src/main/java/com/google/cloud/bigtable/dataflow/example/SourceRowCount.java 
    options.setRegion("us-central1");
    Pipeline p = Pipeline.create(options);

    p.apply(Read.from(CloudBigtableIO.read(config)))
        .apply(Count.<Result>globally())
        .apply(ParDo.of(stringifier))
        .apply(TextIO.write().to(options.getResultLocation()));
    // [END bigtable_dataflow_connector_scan_config]

    p.run().waitUntilFinish();

    // Once this is done, you can get the result file via "gsutil cp <resultLocation>-00000-of-00001"
  }
