# STEP 0) 
$ git clone https://github.com/yennanliu/spark-scala-word-count.git && cd spark-scala-word-count 

# STEP 1) download the used dependencies.
$ sbt clean compile

# STEP 2) run spark word count via `sbt run`
$ sbt run

# STEP 3) create jars from spark scala scriots 
$ sbt assembly

# STEP 4) run spark word count via `spark submit`
$ spark-submit /Users/$USER/spark-scala-word-count/target/scala-2.11/spark-scala-word-count-assembly-1.0.jar

# STEP 0) 
$ git clone https://github.com/yennanliu/spark-scala-word-count.git

# STEP 1) 
$ cd spark-scala-word-count

# STEP 2) docker build 
$ docker build . -t spark_env

# STEP 3) ONE COMMAND : run the docker env and sbt compile and sbt run and assembly once 
$ docker run  --mount \

# STEP 3') : STEP BY STEP : access docker -> sbt clean compile -> sbt run -> sbt assembly -> spark-submit
