Some questions around E2E Tests

[npow]

Hi, I am trying to write some E2E tests for my PR which adds DynamoDB as a reader/writer. I'm getting a FileNotFoundException, which from my experience means that the files do not exist on HDFS. Looking at the e2e/elasticsearch example, I do not see how the example files are made accessible to the docker containers, or how the tests use the updated JAR with the latest code. So I have the following questions:

1. How do I make my newly added example files available to the spark-submit image?
2. How do I run the tests with the updated metorikku.jar file?

- SUBMIT_COMMAND=spark-submit --packages com.audienceproject:spark-dynamodb_2.12:1.1.2 --class com.yotpo.metorikku.Metorikku metorikku.jar -c examples/dynamodb/movies.yaml

3. I am trying to use dynamodb-local for the tests, but that requires additional configuration options to change the endpoint URL to be local. What is the recommended way to add test specific configs to the examples?

Error snippet:

dynamodb-spark-submit-1  | Exception in thread "main" java.io.FileNotFoundException: File examples/dynamodb/movies.yaml does not exist
