Microsoft: Using Microsoft R Server Operationalization on HDInsight

R Server on HDInsight cluster allows R scripts to use Spark and MapReduce to run distributed computations. You can develop a model and operationalize the model to make predictions by configuring Edge Node as One-Box. We have One-Click Deploy ARM Templates using which you can create R Server on HDInsight Cluster with EdgeNode configured as One-Box. If you already have R Server on HDInsight Cluster, you can configure operationalization using Admin Utility.

Once you have configured Operationalization, you can use the mrsdeploy package on your local machine Microsoft R Client to connect to the Operationalization on edge node and start using its features like remote execution and web-services. This article focuses on how to connect to Operationalization feature depending on whether your cluster is set up on a virtual network or not.

RServer Cluster on virtual network

  • Create a Virtual Network + Subnet before creating the HDI cluster (The VNET and the HDI Cluster must be created in the same resource group).
  • When defining the HDI cluster via the Azure Portal, go into the “Advanced Settings” and specify to use the VNET and Subnet that were previously defined.
  • Once the cluster is created, select the resource group that was used, and select the “virtual network” that was created.
  • From there, a list of the attached devices will be shown.  Select the edge node from the list, and then select IP configurations.
  • Select the default IP configuration assigned to the edge node, and then change “Public IP Address” from disabled to enabled.
  • Create a new Public IP Address and select it.  Click the “save” button to save the changes.
  • Go back to the “edge node” and select “network security group” It should show “none”.  Select the network security group, and add an “inbound security rule” that opens port 12800.
