Step 2: Install the MapR Package Key

About this task

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.

Procedure

To install the MapR package key, issue the command appropriate for your Linux distribution:

CentOS/RedHat/Oracle Linux

rpm --import http://package.mapr.com/releases/pub/maprgpg.key

Ubuntu

wget -O - http://package.mapr.com/releases/pub/maprgpg.key | sudo apt-key add -
