Running test failed with Connection refused exception

[asmelashteka]

I'm trying docker-spark on Ubuntu 14.04. When running the test
spark-shell --master yarn-client --driver-memory 1g --executor-memory 1g --executor-cores 1

It throws the following exception:

java.net.ConnectException: Call From spark/172.17.0.5 to spark:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

Is it possible that you are running on a virtual machine with not enough memory? You need more than 2GB of memory to run this container, I have found.
