Gary Helmling resolved HBASE-4372.
----------------------------------

    Resolution: Invalid

I think you misunderstand the purpose of User.IS_SECURE_HADOOP.  It is there to differentiate
between API incompatible versions of UserGroupInformation from vanilla 0.20 to secure 0.20+
using reflection.

Whether or not kerberos authentication is enabled makes no difference in determining whether
we need to call UserGroupInformation.getCurrentUGI() vs. UserGroupInformation.getCurrentUser(),
for example.

If you simply want access to whether or not secure authentication is enabled, there is a patch
against HBASE-4180 that adds a User.isSecurityEnabled() method.

> Currently, IS_SECURE_HADOOP is set to true if UserGroupInformation has a method isSecurityEnabled.
It should be set to true only if security is turned on as well.
