-- | This operation returns information about a job you previously initiated,
-- including the job initiation date, the user who initiated the job, the job
-- status code/message and the Amazon SNS topic to notify after Amazon Glacier
-- completes the job. For more information about initiating a job, see 'InitiateJob'.
--
-- This operation enables you to check the status of your job. However, it is
-- strongly recommended that you set up an Amazon SNS topic and specify it in
-- your initiate job request so that Amazon Glacier can notify the topic after
-- it completes the job.
--
-- A job ID will not expire for at least 24 hours after Amazon Glacier
-- completes the job.
--
-- An AWS account has full permission to perform all operations (actions).
-- However, AWS Identity and Access Management (IAM) users don't have any
-- permissions by default. You must grant them explicit permission to perform
-- specific actions. For more information, see <http://docs.aws.amazon.com/amazonglacier/latest/dev/using-iam-with-amazon-glacier.html Access Control Using AWS Identityand Access Management (IAM)>.
