Step 2: Install the MapR Package Key

MapR packages are cryptographically signed. Before you can install MapR packages, you must install the MapR package key, maprgpg.key. Note: For SUSE only, you do not have to install the key because zypper allows package installation with or without the key.
To install the MapR package key, issue the command appropriate for your Linux distribution:
  • CentOS/RedHat/Oracle Linux

    rpm --import
  • Ubuntu

    wget -O - | sudo apt-key add -
