+== Declaring Hadoop dependencies
+
+Spring for Apache Hadoop provides necessary transitive dependencies via
+the project's Maven POM files. The default is using Apache Hadoop 2.2.x
+but there are additional versions available for other Hadoop distributions
+like Pivotal HD, Hortonworks Data Platform or Cloudera CDH. By specifying
+the desired version, your project will automatically resolve the correct
+Hadoop distribution dependencies.
