Accessing Parameters Using getResolvedOptions

The AWS Glue getResolvedOptions(args, options) utility function gives you access to the arguments that are passed to your script when you run a job. To use this function, start by importing it from the AWS Glue utils module, along with the sys module:

import sys from awsglue.utils import getResolvedOptions

getResolvedOptions(args, options)

  • args – The list of arguments contained in sys.argv.

  • options – A Python array of the argument names that you want to retrieve.

Example Retrieving arguments passed to a JobRun

Suppose that you created a JobRun in a script, perhaps within a Lambda function:

response = client.start_job_run( JobName = 'my_test_Job', Arguments = { '--day_partition_key': 'partition_0', '--hour_partition_key': 'partition_1', '--day_partition_value': day_partition_value, '--hour_partition_value': hour_partition_value } )

To retrieve the arguments that are passed, you can use the getResolvedOptions function as follows:

import sys from awsglue.utils import getResolvedOptions args = getResolvedOptions(sys.argv, ['JOB_NAME', 'day_partition_key', 'hour_partition_key', 'day_partition_value', 'hour_partition_value']) print "The day-partition key is: ", args['day_partition_key'] print "and the day-partition value is: ", args['day_partition_value']
