How to use Boto3 to delete a glue job from AWS Glue?
Problem Statement − Use boto3 library in Python to delete a glue job, created in your account.
Example − Delete a glue job ‘transfer_from_s3’ that is created in your account.
Approach/Algorithm to solve this problem
Step 1 − Import boto3 and botocore exceptions to handle exceptions.
Step 2 − Pass the parameter job_name that should be deleted from AWS Glue Catalog.
Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.
Step 4 − Create an AWS client for glue.
Step 5 − Now use delete_job function and pass the job_name as JobName parameter.
Step 6 − It will delete the job and return the response metadata.
Step 7 − Handle the generic exception if something went wrong while checking the job.
Note − After the completion of this operation, it deletes a specified job definition. If job is not found in AWS Glue, it doesn’t throw any exception and output is similar if it deletes any.
Example
Use the following code to delete a glue job from AWS Glue:
import boto3
from botocore.exceptions import ClientError
def delete_a_glue_job(job_name):
session = boto3.session.Session()
glue_client = session.client('glue')
try:
response = glue_client.delelte_job(JobName=job_name)
return response
except ClientError as e:
raise Exception( "boto3 client error in delete_a_glue_job: " + e.__str__())
except Exception as e:
raise Exception( "Unexpected error in delete_a_glue_job: " + e.__str__())
print(delete_a_glue_job("transfer_from_s3"))Output
{'JobName': ' transfer_from_s3', 'ResponseMetadata': {'RequestId':
