Once the config changes are applied, proceed to restart **Hadoop** services.

The contents of this page have been migrated to the new [MinIO Documentation: Bucket Replication](https://min.io/docs/minio/linux/administration/bucket-replication.html) page. The [Bucket Replication](https://min.io/docs/minio/linux/administration/bucket-replication/bucket-replication-requirements.html) page references dedicated tutorials for configuring one-way "Active-Passive" and two-way "Active-Active" bucket replication.

### Errors

XML error response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_Errors)

## Sample `POST` Request

```

	return subtle.ConstantTimeCompare([]byte(sig1), []byte(sig2)) == 1
}

//   - http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-HTTPPOSTConstructPolicy.html
//
// returns ErrNone if the signature matches.

	// Server region.

// credentials for regular users on Minio.
