Spark client docker image


This repository contains a docker image to run Apache Spark client.

To run simple spark shell :

docker run -it epahomov/docker-spark:lightweighted /spark/bin/spark-shell

To run simple python spark shell (known as pyspark) :

docker run -it epahomov/docker-spark:lightweighted /spark/bin/pyspark

Examples before used lightweighted version of this image. It's very small, so it would download very fast, but it's not very flexible. All next examples would be with default version

To run simple spark R shell :

docker run -it epahomov/docker-spark /spark/bin/sparkR

To run simple spark sql shell :

docker run -it epahomov/docker-spark /spark/bin/spark-sql

To run simple spark shell with some changed properties like here :

docker run -it epahomov/docker-spark /spark/bin/spark-shell  --master local[4]

To run simple spark shell with changed spark-defaults.conf do:

printf "spark.master local[4] \nspark.executor.cores 4" > spark-defaults.conf
sudo docker run -v $(pwd)/spark-defaults.conf:/spark/conf/spark-defaults.conf -it epahomov/docker-spark /spark/bin/spark-shell

First line write conf into file spark-defaults.conf, and second line mount this file from host file system to filesystem in container and puts it in conf directory.

To be able to use spark ui, add " -p 4040:4040 " argument:

docker run -ti -p 4040:4040 epahomov/docker-spark /spark/bin/spark-shell

To run some python script do:

echo "import pyspark\nprint(pyspark.SparkContext().parallelize(range(0, 10)).count())" > count.py
docker run -it -p 4040:4040 -v $(pwd)/count.py:/count.py epahomov/docker-spark /spark/bin/spark-submit /count.py

docker run -v $(pwd)/hadoop:/etc/hadoop/conf -e "HADOOP_CONF_DIR=/etc/hadoop/conf" --net=host  -it epahomov/docker-spark /spark/bin/spark-shell --master yarn-client
