Reported by Parth:
"One issue that our ranger team has found is that session.host returns InetAddress.toString() which is of the format hostname/IP. This means all the acls that wants to specify hosts will have to specify host in hostNaem/IP format. We can either make session.host return ip or host name or change the authorizer to evaluate against all 3 “host/ip”, “host”, “IP”."
Jun suggested we use IP instead of hostname/IP.
