> visit response of RangerClient.findRoles, you will get en exception
> Sample code:
> {code:java}
> // code placeholder
> RangerClient rangerClient = new RangerClient(hostName, userName, password);
> List<RangerRole> allRoles = rangerClient.findRoles(null);
> LOG.info("List of Roles {}", gsonBuilder.toJson(allRoles));
> for (RangerRole role : allRoles) {
> LOG.info("Role is : {}", role.getName());
