Kihwal Lee commented on HDFS-6219:
----------------------------------
Suppose we have a chain of proxies:
{panel} X-Forwarded-For: origin_ip_addr, proxy1_ip_addr, proxy2_ip_addr
{panel}
Do you think we should check both {{proxy1_ip_addr}} and {{proxy2_ip_addr}}? Or
since the last proxy is a "trusted" proxy, can we assume access to it is
controlled?
> Proxy superuser configuration should use true client IP for address checks

> Similar to HDFS-6218, the trusted proxies should use X-Forwarded-For when
> performing superuser checks so oozie can use webhdfs via a http proxy.
