Boto - How to delete a record set from route53 -Tried to delete resource record set but it was not found

Question

I am using the following to delete route53 records. I get no error messages.

conn = Route53Connection(aws_access_key_id, aws_secret_access_key)
changes = ResourceRecordSets(conn, zone_id)
change = changes.add_change("DELETE",sub_domain, "A", 60,weight=weight,identifier=identifier)
change.add_value(ip_old)
changes.commit()

all required fields are present and they match..weight, identifier, ttl=60 etc.\

e.g.

test.com. A 111.111.111.111 60 1 id1
test.com. A 111.111.111.222 60 1 id2

I want to delete 111.111.111.222 and the record set.

So, what is the proper way to delete a record set?

For a record set, I will have multiple values that are distinguished by a unique identifier. When an ip address becomes in active I want to remove from route53. I am using a a poor mans load balancing.

Here is the meta of the record  want to delete.  
{'alias_dns_name': None,
  'alias_hosted_zone_id': None,
  'identifier': u'15754-1',
  'name': u'hui.com.',
  'resource_records': [u'103.4.xxx.xxx'],
  'ttl': u'60',
  'type': u'A',
  'weight': u'1'}

Answer 1

Are you sure you need all of those parameters for add_change?

Look at add_change here.

Default parameters are given to the function, so you may be over-specifying by providing weight and TTL.

Try leaving weight and TTL out (you may need to keep identifier). This blog provides a simple example of deleting records:

Also, I can't see the values of your parameters that you're passing, but ensure their integrity and try including a '.' at the end of your subdomain

Answer 2

I tried similar example and had to specify all fields including weight and ttl for a successful deletion. (By keeping it default, it did not work). Could not produce the original problem with weighted DNS record and explicitly passed ttl.
