Spark Cassandra Stress

A tool for testing the DataStax Spark Cassandra Connector against both ApacheCassandra (TM) and DataStax Enterprise (DSE) with either bundled libraries fromDSE, Maven, or the connector built from source!BuildingThis project is built using Gradle and can be built in three exciting ways:Using the Connector and Spark libraries installed by DataStax EnterpriseUsing libraries downloaded from mavenUsing libraries assembled fresh from your local Spark Cassandra Connector RepositoryThe jar can be built using./gradlew jar -Pagainst=[type]Where type is one of dse,maven or sourceDSE OptionsDSE libraries are located by looking for the installation of DSE on your machine.Change environment variables DSE_HOME and DSE_RESOURCES if your installationdiffers from the default.DefaultsDSE_HOME=$HOME/dseDSE_RESOURCES=$HOME/dse/resourcesMaven OptionsWhen getting libraries from Maven we need to specify the Connector version andSpark Version libraries to compile against. Change environment variablesCONNECTOR_VERSION and SPARK_VERSION to the artifacts you would like touse.DefaultsCONNECTOR_VERSION=1.2.0-rc2SPARK_VERSION=1.2.1Source OptionsGradle will attempt to clean and build the assembly jar for the Spark Connectorlooking for the repository in environment variable SPARKCC_HOME. This willbuild whatever commit the connector is currently at.DefaultSPARKCC_HOME=$HOME/repos/spark-cassandra-connector/RunningThere are many options which can be used to configure your run ofSpark Cassandra Stress but the two main invocations are either usingdse spark-submit or spark-submit.See the run.sh script for examples or use it to launch the program../run.sh [dse|apache] --helpWill bring up the built in help.LicenseCopyright 2014-17, DataStax, Inc.Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
