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