# Spark Boilerplate
|
||||
This is a boilerplate project for Apache Spark. The related blog post can be found at [https://www.barrelsofdata.com/spark-boilerplate-using-scala](https://www.barrelsofdata.com/spark-boilerplate-using-scala)
|
||||
|
||||
## Build instructions
|
||||
From the root of the project execute the below commands
|
||||
- To clear all compiled classes, build and log directories
|
||||
```shell script
|
||||
./gradlew clean
|
||||
```
|
||||
- To run tests
|
||||
```shell script
|
||||
./gradlew test
|
||||
```
|
||||
- To build jar
|
||||
```shell script
|
||||
./gradlew shadowJar
|
||||
```
|
||||
- All combined
|
||||
```shell script
|
||||
./gradlew clean test shadowJar
|
||||
```
|
||||
|
||||
## Run
|
||||
```shell script
|
||||
spark-submit --master yarn --deploy-mode cluster build/libs/spark-boilerplate-1.0.jar
|
||||
```
