Rohith Sharma K S commented on MAPREDUCE-7038:
----------------------------------------------
It is done intentionally for secure login from configured hostname rather than
getting from localhost. In case of VIP machines, doing as per patch disregard
VIP address. This reverts YARN-1590, pls take a look at it.
> JHS uses service config to identify local hostname

> In JobHistoryServer.doSecureLogin(), the local hostname is got by calling
> getBindAddress() which gets the hostname that is defined by the config
> yarn.mapreduce.jobhistory.address. This is a bug and doSecureLogin should
> just get local host name directly instead of this way.
