ROOT CAUSE:

Ranger Hive policies http url calls were taking forever to return results Ranger makes a lot of calls to urllib2.urlopen(request) that don't have a timeout in Ambari 2.0 Opened Ambari BUG to put time=5 in the ranger_function.py file.

https://hortonworks.jira.com/browse/BUG-46275

RESOLUTION:

1) Edit /usr/lib/python2.6/site-packages/resource-management/libraries/functions/ranger_functions.py and copy to all host to be safe (only Hive nodes)

all urllib2.urlopen(request) do urllib2.urlopen(request, timeout=5)

2) Delete duplicate x_group_users - MYSQL https://hortonworks.jira.com/browse/BUG-43119
