Install R Server 9.1 on the Cloudera distribution of Apache Hadoop (CDH)

Cloudera offers a parcel installation methodology for adding services and features to a cluster. If you prefer parcel installation over the regular install script used for deploying R Server on other Hadoop distributions, you can use functionality we provide to create the parcel.
If you've used parcel installation in previous releases of Microsoft R Server, the 9.1.0 release is enhanced in two respects. First, instead of using pre-built parcels downloaded from Microsoft, you can generate your own parcel using a new generate_mrs_parcel.sh script. Secondly, we added support for Custom Service Descriptors (CSDs), which means you can now deploy, configure, and monitor R Server in CDH as a managed service in Cloudera Manager.
The new revised workflow for parcel installation is a two-part exercise:
- Part 1: At the console, run script to output parcel and CSD files
- Part 2: In Cloudera Manager, deploy parcels and add MRS as a managed service
Download and unpacking the distribution remains the same. Instructions are included in Part 1.
Feature restrictions in a parcel installation
R Server includes two packages, MicrosoftML and mrsdeploy, that either cannot be included in the parcel, or included only if the underlying operating system is a specific platform and version.
MicrosoftMLis conditionally available. The package can be included in the parcel if the underlying operating system is CentOS/RHEL 7.x. If CDH runs on any other operating system, including an earlier version of RHEL, theMicrosoftMLpackage cannot be included.mrsdeployis excluded from a parcel installation. This package has a .NET Core dependency and cannot be added to a parcel.
The workaround is to perform a manual installation of individual packages. For instructions, see Manual package installation.
