Libraries and tools for interoperability between Apache Hadoop related open-source software and Google Cloud Platform.
Google Cloud Storage connector for Apache Hadoop
The Google Cloud Storage connector for Hadoop enables running MapReduce jobs directly on data in Google Cloud Storage by implementing the Hadoop FileSystem interface. For details, see the README.
Google BigQuery connector for Apache Hadoop MapReduce
The Google BigQuery connector for Hadoop MapReduce enables running MapReduce jobs on data in BigQuery by implementing the InputFormat & OutputFormat interfaces. For more details see the documentation
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 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: ./mvnw -P hadoop2 clean package # with Hadoop 3 and YARN support: ./mvnw -P hadoop3 clean package
In order to verify test coverage for specific Hadoop version, run the following commands from the main directory:
# with Hadoop 2 and YARN support: ./mvnw -P hadoop2 -P coverage clean verify # with Hadoop 3 and YARN support: ./mvnw -P hadoop3 -P coverage clean verify
The Cloud Storage connector JAR can be found in
gcs/target/. The BigQuery
connector JAR can be found in
Building the Google Cloud Pub/Sub connector
Building the Pub/Sub Connector is described in its README.
Adding the Cloud Storage 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
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>hadoop2-2.0.0</version> <!-- or, for BigQuery: --> <artifactId>bigquery-connector</artifactId> <version>hadoop2-1.0.0</version> </dependency>
