For Revolution R Enterprise installations into Cloudera CDH clusters, there are two possible installation methods for CDH, a package (RPM-based) installation and Cloudera's parcel-based installation performed using Cloudera Manager. Revolution R Enterprise for Cloudera platforms is available in both package types. The download letter and installation documentation states:
IMPORTANT: Cloudera Hadoop can be installed in two ways, either by packages or by parcels using Cloudera Manager. If your Hadoop was installed via packages, you must NOT use the Revolution R Enterprise parcel installer.
Additional clarification is needed for this requirement. If Cloudera Hadoop was installed using parcels, then Revolution R Enterprise must also be installed using parcels. Mixed installation types are not supported.
