3.2.1. Check Your Prerequisites

Select a local mirror server host with the following characteristics:

  • This server runs on either CentOS/RHEL/Oracle Linux 5.x or 6.x, SLES 11, or Ubuntu 12 and has several GB of storage available.

  • The local mirror server and the cluster nodes must have the same OS. If they are not running CentOS or RHEL, the mirror server must not be a member of the Hadoop cluster.

    [Note]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.

  • Ensure that the mirror server has yum installed.

  • Add the yum-utils and createrepo packages on the mirror server.

    yum install yum-utils createrepo
