awsglue.job.Job.init arguments

[don1uppa]

I am using the code fragment below and the job.init call is failing with an error while getting security configuration. (see log below). I'm not suprised by the error since I can't find documentation as to the args that need to be supplied. I did find https://docs.aws.amazon.com/glue/latest/dg/aws-glue-programming-etl-glue-arguments.html but the essential parameters are missing: (IAM_ROLE, connections, etc.) . When I look at the AWS Glue Studio job editor there is a lot of Job context established in the "Job Details" tab. I expect that I need to pass similar information to job.init.

I'm trying to do local debugging of glue jobs as suggested by https://aws.amazon.com/blogs/big-data/developing-aws-glue-etl-jobs-locally-using-a-container/

Any help would be appreciated.

Code:
args = getResolvedOptions(sys.argv, ['JOB_NAME'])
sc = SparkContext()
glueContext = GlueContext(sc)
spark = glueContext.spark_session
job = Job(glueContext)
job.init(args['JOB_NAME'], args)

LOG:
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

So finally figured out that the JOB_NAME needs to reference an existing glue job.
