Why can't I delete kvstore collections using the REST API via Python?

pembleton — Thu, 02 Apr 2015 10:19:05 GMT

I'm trying to delete kvstore collection using REST API via Python:

url = "https://localhost:8089/servicesNS/nobody/myapp/storage/collections/config/deleteme"
request = urllib2.Request(url, headers = {"Authorization" : "Splunk "})
request.get_method = lambda: "DELETE"
results = urllib2.urlopen(request)

This returns HTTP Error 400: Bad request.

The code works for other kvstore functions (when changing the URL) such as deleting collection's data, and I used the correct URL according to the documentation so I can't figure out why this doesn't work.

What happens if you make the same request using curl? Also, likely there is some output together with the 400 status code - can you post it here?

i found this frustrating too. you actually have to POST the option as shown in the CURL examples in the docs.

the way i do it is using splunk's rest.simpleRequest method. strangely, i always seem to misplace the link for the SDK, but here's an example:
http://answers.splunk.com/answers/144000/modifying-acl-saved-search-permissions-through-rest-api-using-python.html

it's not ideal - but perhaps you could first retrieve all the data points in that collection, and then iteratively delete them?

query_uri = '/servicesNS/nobody/<app>/storage/collections/data/<kvstore>'
serverResponse, serverContent = rest.simpleRequest(query_uri, sessionKey=sessionKey)
for result in serverContent:
removal_uri = '/servicesNS/nobody/<app>/storage/collections/data/<kvstore>/%s' % result['_key']
    serverResponse, serverContent = rest.simpleRequest(removal_uri, sessionKey=sessionKey, method='DELETE')

maybe you can also leverage one of the answers from my similar question:

I cannot delete either. I get an error:

curl -k -s -u admin:changeme https://localhost:8089/servicesNS/nobody/myapp/storage/collections/config/test_collection_collection -X DELETE

<msg type="ERROR">Object id=test_collection_collection cannot be deleted in config=collections.</msg>
