Apache-ranger python library JSONDecoder error

Question

So i'm trying to create a policy using the ranger python client, and this is my code (redacted confidential info for security purposes)

from apache_ranger.model.ranger_service import *
from apache_ranger.client.ranger_client import *
from apache_ranger.model.ranger_policy  import *


ranger_url  = 'http://************.com:***'
ranger_auth = ('**********', '**********')

ranger = RangerClient(ranger_url, ranger_auth)

policy           = RangerPolicy()
policy.service   = 'starburst-enterprise'
policy.name      = 'test_policy'
policy.resources = { 'database': RangerPolicyResource({ 'values': ['hive'] }),
                     'table':    RangerPolicyResource({ 'values': ['uber_rides'] }),
                     'column':   RangerPolicyResource({ 'values': ['*'] }) }

allowItem1          = RangerPolicyItem()
allowItem1.groups   = [ 'Data Product Owner' ]
allowItem1.accesses = [ RangerPolicyItemAccess({ 'type': 'select' }) ]

denyItem1          = RangerPolicyItem()
denyItem1.groups    = [ 'Data Product Owner' ]
denyItem1.accesses = [ RangerPolicyItemAccess({ 'type': 'drop' }) ]

policy.policyItems     = [ allowItem1 ]
policy.denyPolicyItems = [ denyItem1 ]

print('Creating policy: name=' + policy.name)

created_policy = ranger.create_policy(policy)

print('    created policy: name=' + created_policy.name + ', id=' + str(created_policy.id))

But i receive this error, When i tried to debug it i found that, the reason it was going for an exception is because the http.post method inside the ranger_clien.py was returning a response (<Response [400]>) that is not handled by any of the if or elifs blocks hence it goes to else block and enters RaiseServiceException(), when i dug deeper i found some comments in the function that gives JSONDecoder error and it said that exception would be raised only if JSON input is not valid or if simplejson is not installed.

Answer 1

Figured out the issue i just had to pass 'https' in ranger_url instead of 'http'
