summary: In this page, we go over how to configure hoodie with Google Cloud Storage.
---
Hoodie works with HDFS by default and GCS **regional** buckets provide an HDFS API with strong consistency.

## GCS Configs

There are two configurations required for Hoodie GCS compatibility:

- Adding GCS Credentials for Hoodie
- Adding required jars to classpath

### GCS Credentials

Add the required configs in your core-site.xml from where Hoodie can fetch them. Replace the `fs.defaultFS` with your GCS bucket name and Hoodie should be able to read/write from the bucket.

```xml
  <property>
    <name>fs.defaultFS</name>
    <value>gs://hoodie-bucket</value>
  </property>

  <property>
    <name>fs.gs.impl</name>
    <value>com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem</value>
    <description>The FileSystem for gs: (GCS) uris.</description>
  </property>

  <property>
    <name>fs.AbstractFileSystem.gs.impl</name>
    <value>com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS</value>
    <description>The AbstractFileSystem for gs: (GCS) uris.</description>
  </property>

  <property>
    <name>fs.gs.project.id</name>
    <value>GCS_PROJECT_ID</value>
  </property>
  <property>
    <name>google.cloud.auth.service.account.enable</name>
    <value>true</value>
  </property>
  <property>
    <name>google.cloud.auth.service.account.email</name>
    <value>GCS_SERVICE_ACCOUNT_EMAIL</value>
  </property>
  <property>
    <name>google.cloud.auth.service.account.keyfile</name>
    <value>GCS_SERVICE_ACCOUNT_KEYFILE</value>
  </property>
```
