Setting up the install machine

The first step in the installation process is to set up the install machine.

1. Select one machine in your cluster to be the install machine.
   This can be any machine in your cluster that has the following:

   • OEL 6 or RHEL 6 installed
   • Password-less sudo-to-root enabled for the Linux user who will run the installer
   • Bash set as the default shell for the Linux user who will run the installer
   • JDK 1.7.0_67+ or JDK 1.8.0_45+ installed
   • Perl 5.10+ with multithreading installed
   • Password-less SSH enabled for the Linux user who will run the installer so that they can log in to all other nodes in the cluster (including Hadoop nodes)
2. Choose an existing directory or create a new one to be the installation source directory.
   You'll perform the entire installation process from this directory. Its name and location are arbitrary and it must contain at least 10GB of free space.
3. Within the installation source directory, create a new directory named packages.
