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](gcs/README.md).

## Unreleased Changes

This Readme may include documentation for changes that haven't been released yet.  The latest release's documentation and source code are found here.

## Building the Cloud Storage connector

> Note that build requires Java 11+ and fails with older Java versions.

To build the connector for specific Hadoop version, run the following commands

from the main directory:

```bash

./mvnw clean package

```

In order to verify test coverage for specific Hadoop version, run the following

commands from the main directory:

```bash

./mvnw -P coverage clean verify

```

The Cloud Storage connector JAR can be found in `gcs/target/` directory.

## Adding the Cloud Storage connector to your build

Maven group ID is `com.google.cloud.bigdataoss` and artifact ID for Cloud

Storage connector is `gcs-connector`.

To add a dependency on Cloud Storage connector using Maven, use the following:

```xml

  com.google.cloud.bigdataoss

  gcs-connector

  ${next-gcs-connector-release-tag}

```
