AWS glacier delete job
The AWS Glacier service does not provide a way to delete a job.  You can:

Initiate a job
Describe a job
Get the output of a job
List all of your jobs

The Glacier service manages the jobs associated with an vault.
I have started a retrival job for an archive stored in one of my vaults on 
Glacier AWS.
It turns out that I do not need to resurrect and download that archive any more.
Is there a way to stop and/or delete my Glacier job?
I am using boto and I cannot seem to find a suitable function.
Thanks
