+# Accessing Openstack Swift storage from Spark
+
+Spark's file interface allows it to process data in Openstack Swift using
the same URI formats that are supported for Hadoop. You can specify a path in
Swift as input through a URI of the form
`swift://<container.service_provider>/path`. You will also need to set your
Swift security credentials, through `SparkContext.hadoopConfiguration`.

+#Configuring Hadoop to use Openstack Swift
+Openstack Swift driver was merged in Hadoop verion 2.3.0 ([Swift
driver](https://issues.apache.org/jira/browse/HADOOP-8545)) Users that wish to
use previous Hadoop versions will need to configure Swift driver manually.
+<h2>Hadoop 2.3.0 and above.</h2>
+An Openstack Swift driver was merged into Haddop 2.3.0 . Current Hadoop
driver requieres Swift to use Keystone authentication. There are additional
efforts to support temp auth for Hadoop
[Hadoop-10420](https://issues.apache.org/jira/browse/HADOOP-10420).
+To configure Hadoop to work with Swift one need to modify core-sites.xml
of Hadoop and setup Swift FS.

+ <configuration>
+ <property>
+ <name>fs.swift.impl</name>
+
<value>org.apache.hadoop.fs.swift.snative.SwiftNativeFileSystem</value>
+ </property>
+ </configuration>

Is the swift jar not included in hadoop-client? Is there a way to specify
this through Maven dependencies rather than manually including the path?
