----------------------------------------

             Summary: Incorrect formated external url in ranger configuration - causes Namenode startup failure
                 Key: AMBARI-17118
                 URL: https://issues.apache.org/jira/browse/AMBARI-17118
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Mugdha Varadkar
            Assignee: Mugdha Varadkar
             Fix For: 2.4.0


STR:
1. install ambari and HDP with HDFS,YARN,HIVE
2. install ranger and configure *External URL* https://c6401.ambari.apache.org:6182/ ( means slash at the end of the URL which is allowed without any problem and installation is done successfully)
3. enable ranger plugin in hdfs config and restart it 

Result: NN startup fails and even after failure , error message in stack trace is confusing 

ERROR:
======
File "/usr/lib/python2.6/site-packages/resource_management/libraries/functions/ranger_functions.py", line 108, in create_ranger_repository
    raise Fail('Ambari admin username and password are blank ')
resource_management.core.exceptions.Fail: Ambari admin username and password are blank


but actual reason is a slash at the end of the External URL,


it fails the following point in usr/lib/python2.6/site-packages/resource_management/libraries/functions/ranger_functions.py:

result = urllib2.urlopen(request)
