how to set environment (without docker)

1. download xgboost4j-0.82 jar files from xgboost-jars

3. rename to xgboost4j-0.82.jar and xgboost4j-spark-0.82.jar respectively
4. set your SPARK_HOME and JAVA_HOME in pyspark/start.sh
5. [opt] change spark-submit parameters if needed

Appendix

run the program within docker

how to set environment (docker)

build images from docker file (~3GB)

it takes some time to build the images ...

cd docker
docker build -t xgb:latest . --no-cache

start docker container using images, go to project directory

docker run -i -t xgb:latest /bin/bash
cd xgboost-python-pyspark
