<title>Data processing service</title>
<para>The Data processing service for OpenStack (sahara) aims to provide
users with simple means to provision data processing (Hadoop, Spark)
clusters by specifying several parameters like Hadoop version, cluster
topology, nodes hardware details and a few more. After user fills in
all the parameters, the Data processing service deploys the cluster in a
few minutes. Also sahara provides means to scale already provisioned
clusters by adding/removing worker nodes on demand.
