Tokens should use original hostname provided instead of ip
----------------------------------------------------------
Key: HADOOP-7510
URL: https://issues.apache.org/jira/browse/HADOOP-7510
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Fix For: 0.20.205.0
Tokens currently store the ip:port of the remote server. This precludes tokens
from being used after a host's ip is changed. Tokens should store the hostname
used to make the RPC connection. This will enable new processes to use their
existing tokens.
