Select a mirror server host with the following characteristics:

This server runs on either CentOS (v5.x, v6.x) or RHEL (v5.x, v6.x) and has several GB of storage available. [For Beta, only RHEL/CentOS/Oracle Linux 6.x is supported]
This server and the cluster nodes are all running the same OS.
Note
To support repository mirroring for heterogeneous clusters requires a more complex procedure than the one documented here.
The firewall allows all cluster nodes (the servers on which you want to install HDP) to access this server.
