+## <a name="upload"></a>Configuring S3A for S3 on Outposts
+
+S3A now supports [S3 on
Outposts](https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3onOutposts.html).
+Accessing data through an access point is done by using its Amazon Resource
Name (ARN), as opposed to just the bucket name.
+The only supported storage class on Outposts is **OUTPOSTS**, and by default
objects are encrypted with
[SSE-S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-outposts-data-encryption.html).
+You can set the Access Point ARN property using the following per bucket
configuration property:
+
+```xml
+<property>
+ <name>fs.s3a.bucket.sample-outpost-bucket.accesspoint.arn</name>
+
<value>arn:aws:s3-outposts:region:account-id:outpost/outpost-id/accesspoint/accesspoint-name</value>
+ <description>Configure S3a traffic to use this S3 on Outposts Access Point
ARN</description>
+</property>
+```
+
+This configures access to the `sample-outpost-bucket` for S3A to go through
the new Access Point ARN. So, for example `s3a://sample-outpost-bucket/key`
will now use your configured ARN when getting data from S3 on Outpost instead
of your bucket.
