> 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)
