+title: Accessing OpenStack Swift from Spark
+---
+
+Spark's support for Hadoop InputFormat allows it to process data in
OpenStack Swift using the
+same URI formats as in Hadoop. You can specify a path in Swift as input
through a
+URI of the form <code>swift://container.PROVIDER/path</code>. You will
also need to set your
+Swift security credentials, through <code>core-site.xml</code> or via
+<code>SparkContext.hadoopConfiguration</code>.
+Current Swift driver requires Swift to use Keystone authentication method.
+
+# Configuring Swift for Better Data Locality
+
+Although not mandatory, it is recommended to configure the proxy server of
Swift with
+<code>list_endpoints</code> to have better data locality. More information
is
+[available
here](https://github.com/openstack/swift/blob/master/swift/common/middleware/list_endpoints.py).
+
+
+# Dependencies
+
+The Spark application should include <code>hadoop-openstack</code>
dependency.
+For example, for Maven support, add the following to the
<code>pom.xml</code> file:
+
+{% highlight xml %}
+<dependencyManagement>
+ ...
+ <dependency>
+ <groupId>org.apache.hadoop</groupId>
+ <artifactId>hadoop-openstack</artifactId>
+ <version>2.3.0</version>
+ </dependency>
+ ...
+</dependencyManagement>
+{% endhighlight %}
+
+
+# Configuration Parameters
+
+Create <code>core-site.xml</code> and place it inside
<code>/spark/conf</code> directory.
