Answer
- S3/Swift (Without keystone environment)
- All APIs related to GET/HEAD requests for existent objects will succeed.
- All APIs related to new PUT/Overwrite/Delete will fail due to the reason of
Cassandra Driver Error(Unavailable)
- Swift (With keystone environment)
- All APIs will fail due to the reason of
Token generation CQLquery failed.- Swift requires at least 2 ADC nodes online.
- All APIs will fail due to the reason of
