Running RSparkling on Databricks Azure Cluster¶
Sparkling Water, PySparkling and RSparkling can be used on top of Databricks Azure Cluster. This tutorial is the RSparkling.
For Scala Sparkling Water, please visit Running Sparkling Water on Databricks Azure Cluster and for PySparkling, please visit Running PySparkling on Databricks Azure Cluster.
To start Sparkling Water
H2OContext on Databricks Azure, the steps are:
Login into Microsoft Azure Portal
Create Databricks Azure Environment
In order to connect to Databricks from Azure, please make sure you have created user inside Azure Active Directory and using that user for the Databricks Login.
Create the cluster
- For Sparkling Water 3.26.2-2.3 select Spark 2.3.3
It is advised to always use the latest Sparkling Water and Spark version for the given Spark major version.
Create R notebook and attach it to the created cluster. To start
H2OContext, the init part of the notebook should be:
# Install Sparklyr install.packages("sparklyr") # Install RSparkling 2.3.2-2 install.packages("rsparkling", type = "source", repos = "http://h2o-release.s3.amazonaws.com/sparkling-water/rel-2.3/2-2/R") # Install H2O 126.96.36.199 (yau) install.packages("h2o", type = "source", repos = "http://h2o-release.s3.amazonaws.com/h2o/rel-yau/2/R") # Connect to Spark on Databricks library(rsparkling) library(sparklyr) sc <- spark_connect(method = "databricks") # Start H2O context h2o_context(sc)
And voila, we should have
Please note that accessing H2O Flow is not currently supported on Azure Databricks.
