project = "${var.gcp_project}"
region = "${var.region}"
}
resource "google_dataflow_job" "big_data_job" {
#name = "${var.job_name}"
template_gcs_path = "gs://dataflow-templates/wordcount/template_file"
#template_gcs_path = "gs://dataflow-samples/shakespeare/kinglear.txt"
temp_gcs_location = "gs://bucket-60/counts"
max_workers = "${var.max-workers}"
project = "${var.gcp_project}"
zone = "${var.zone}"

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

Answer 1

In your code you've commented out the name argument, but name is required for this resource type.
Remove the leading # from this line
#name = "${var.job_name}"
You've also included name as a parameter to the dataflow template, but that example wordcount template does not have a name parameter, it only has inputFile and output:
inputFile The Cloud Storage input file path.
output The Cloud Storage output file path and prefix.
Remove this part:
parameters {
name = "cloud_dataflow"
}
