Prerequisites

Cluster is available and is already secured with Kerberos.
Slider and ZooKeeper are installed on the cluster.
The Hadoop directory is in the same location on each node so the native binary can be accessed, which supports secure I/O.

	Important
You should have a method to execute commands and upload files on all nodes in the cluster from one "setup" or "jump" node. This can be set up with passwordless ssh (pssh) or by using a FOR loop with a list of nodes. On the "setup" node, add Java tools to the system path. All passwords, user names, and paths in this section of the document are provided as examples unless otherwise noted. Change them for your deployment as appropriate.
