Execute a file in Google Cloud Platform (GCP) bucket using Scala

I'm looking to execute Scala code in text file using GCP with Spark Shell.

Using GCP (Google Cloud Platform), I've done the following:

1. Created a DataProc instance and named it gcp-cluster-091122.

2. Created a Cloud Bucket and named it gcp-bucket-091122p.

3. Created a simple text file called 1.txt and uploaded the file into the recently created GCP bucket, gcp-bucket-091122.

4. Logged onto the VM-instance SSH-in-browser and entered the command spark-shell to access the scala > prompt.

From here, how does one read/execute a particular file uploaded into a GCP bucket? I've researched this topic, but I've been unsuccessful.

I've also used "GCS Fuse" plug-in code to successfully mount the GCP bucket, gcp-bucket-091122 onto a created local file directory in SSH called lfs-directory-091122.

So an additional question would be how to execute a file located in the local file directory using Spark Shell?
