Supported Platforms

Sparkling Water can run on top of Spark in various ways; however, starting Sparkling Water requires different configurations on different environments:

Local

In this case, Sparkling Water runs as a local cluster (Spark master variable points to one of the values local, local[*] or additional local modes available at Spark Master URLs).

Standalone Spark Cluster

YARN

When submitting a Sparkling Water application to a CHD or Apache Hadoop cluster, the command to submit may look like:

./spark-submit --master=yarn --deploy-mode=client --class ai.h2o.sparkling.SparklingWaterDriver
--driver-memory=8G --num-executors=3 --executor-memory=3G --conf "spark.executor.extraClassPath=-Dhdp.version=current"
sparkling-water-assembly-3.46.0.4-1-3.2-all.jar

When submitting a Sparkling Water application to an HDP Cluster, the command to submit may look like:

./spark-submit --master=yarn --deploy-mode=client --class ai.h2o.sparkling.SparklingWaterDriver --conf "spark.yarn.am.extraJavaOptions=-Dhdp.version=current"
--driver-memory=8G --num-executors=3 --executor-memory=3G --conf "spark.executor.extraClassPath=-Dhdp.version=current"
sparkling-water-assembly-3.46.0.4-1-3.2-all.jar

The only difference between the HDP cluster and the CDH and Apache Hadoop clusters is that we need to add -Dhdp.version=current to both the spark.executor.extraClassPath and spark.yarn.am.extraJavaOptions (resp., spark.driver.extraJavaOptions) configuration properties in the HDP case.
