1. are you using docker-compose?
2. how are you running your application? i.e. from IDE, spark-submit, java -jar ...

[Eric Rodriguez]

show your docker-compose.yml plz

also, if you run with gradle you're gonna need to define 127.0.0.1 localhost spark-master on /etc/hosts (assuming u're on mac or linux)
