Google Cloud Pub/Sub connector for Apache Spark Streaming

The Google Cloud Pub/Sub connector for Spark Streaming enables running Spark Streaming Job on topics in Pub/Sub by implementing the InputDStream interface. For more details see the README

Building the Cloud Storage (GCS) and BigQuery connectors

To build the connector for specific Hadoop version, run the following commands from the main directory:

# with Hadoop 2 and YARN support:
mvn -P hadoop2 clean package
# with Hadoop 3 and YARN support:
mvn -P hadoop3 clean package

The GCS connector JAR can be found in gcs/target/. The BigQuery JAR can be found in bigquery/target/.

Building the Google Cloud Pub/Sub connector

Building the Pub/Sub Connector is described in its README.

Adding the Cloud Storage (GCS) and BigQuery connectors to your build

Maven group ID is com.google.cloud.bigdataoss and artifact ID for Cloud Storage connector is gcs-connector and for BigQuery connectors is bigquery-connector.

To add a dependency on one of the connectors using Maven, use the following:

<dependency>
  <groupId>com.google.cloud.bigdataoss</groupId>
  <!-- Cloud Storage: -->
  <artifactId>gcs-connector</artifactId>
  <version>hadoop2-1.9.16</version>
  <!-- or, for BigQuery: -->
  <artifactId>bigquery-connector</artifactId>
  <version>hadoop2-0.13.16</version>
</dependency>
